COLLECTORS INFORMATION
FOR PYRAMIDS

100 & 200 TYPE TELEPHONES

These telephones are normally very collectable if they are original GPO stock. Many of these telephones offered for sale are hybrids, non GPO or replicas. Of course it depends on what you are collecting or the price you want to pay.  An original is shown to the right.

Coloured replicas cost from £90 - £120, whereas a real the GPO green telephone in very good condition will cost as much as £450 and the red £350. Funny prices can also be an indication that the seller knows more than they are letting on!

To the right is a marking from the base of a Telephone No. 162, it was made by Siemens in 1932 with a dial that had figures on it and was a mark 234.  These style of marking are quite normal.

Also look out for the GPO batch stamp - shown later in this document.

Indian produced replicas are very good if you want a pyramid, perfect in condition, coloured and at a very much reduced price. These can generally be identified if they have 1T1 on them, if the handset details have been polished out, if the marking protrude from the handset or if the handset details say "GPO PL'35 No164".

GPO handsets have recessed details (normally sign written GPO Tele 164, with manufacturers code and date, as shown above) whilst some replicas have it protruding.  The picture shows a genuine handset marking on the left, whilst the protruding marking is clearly visible on the right.

Also beware of those telephones that have a line cord entry on the side of the telephone case - genuine GPO telephones have a hole in the lower rear of the case.

Some individuals have been known to spray black telephones green or red. These are generally easy to spot as the paint is thin on the corners and the black case shows through (the GPO never sprayed any cases, they were always replaced). Coloured originals also generally have that transparent look and although some look quite solid. Due to the age of these phones the cases will also be scratched and in some cases chipped. Some original coloured cases are faded (due to light - particularly the reds!) and this causes difficulty in matching broken parts - always check your coloured telephone in daylight.

An Indian conjuring trick was a series of 200-type cases and bases, both of which are visibly under-sized. The result is that the fixing screws in the metal base plates do not line up and must be forced in at an angle. The drawer in the front of the telephone's base is well copied and looks quite realistic; on the other hand the celluloid insert for the dialling code card is not at all convincing. The forks of the cradle rest are of the type fitted to the 162 instrument and look wrong.

Beware of case cracks and damaged handset rests (broken prongs or forks), particularly if coloured, because these are very hard to find.

There are also two patterns of handset rests: the later type had a base that was larger than the neck whilst the early type had a base the exact same size as the neck of the telephone).

The reproduction forks are of thinner proportions than the genuine ones and the rear prongs of the forks may be of different proportions to each other.  Reproduction forks are also closer in design to those used on the Telephone  162. On their underside the repro forks have two circular mould marks raised proud (on genuine originals these are recessed and contain the initials of the firm that moulded them).

Old style - genuine	New style - genuine

Inspect the inside of the telephone to ensure that it has the original wiring and components. Check the diagram pasted to the base is the correct diagram and look at the markings on the components. GPO parts usually had a description and number (i.e. Coil Induction No. 29) whilst privately supplied telephones generally had numbered parts i.e. N103425 (Ericsson part number).

Also check the dates on these components, this will indicate whether the phone is totally original. Expect some parts to be dated differently as many phones were repaired at GPO factories, with parts replaced and then returned to the field. If you are offered a telephone that is supposed to be totally original then check the component dates and manufactures name. These should be the same code and the dates within a couple of years of each other. In particular check the dial - you will have to release the dial from the case to find the date of issue and manufacturers code under the outside edge.

Look for minimal refurbishment and expect to find markings on the bases. A plastic sticker indicates factory refurbishment and a white painted square nearby (shown to the right) would most probably be covering the original markings. This is quite normal. Bases with nothing written on them or cases with transfers are not generally GPO. The only garish thing done to 100 & 200 types was a mirror inside the instruction draw with a red GPO insignia (very rare).

The feet are usually flattened and are uniformly round. Domed feet were never fitted to these phones.

These telephones will work with the UK new style sockets without modification.  All you need is a plug ended cord, possibly a new transmitter and a little bit of wiring.  There is no real reason to remove the innards and replace them with a modern circuit.  The cords and transmitter are relatively cheap compared to getting replacement Bakelite or original parts.

The Telephone 162 needs a Bellset if you want the phone to work properly, whereas the Tele 232 will work perfectly OK without a Bellset as long as you do not want a bell with the telephone.  If a 162 or 232 has a bell inside the case, then it's not original!

The Telephone 162 (and the Candlestick telephone) needs a Bellset No. 1 (wooden) or Bellset No. 25 (Bakelite). These Bellsets consist of bell ringer mechanism, capacitor and an induction coil and are rarely found now days.  A Bellset No. 41 will not work at all!
Do not be misled when looking inside a Tele 162 as it has a metal clad transformer fitted inside. This is normal, it is not an induction coil and will not suffice on it's own.  The picture to the right shows the insides of a Telephone 232 and the Induction Coil is on the right. This coil is paper covered.

The Telephone 232 needs a Bellset No. 26 (contains a bell ringer and capacitor - black is fairly easy to get hold of) if you want a bell to go with the telephone.  Without the bell, the telephone will still function as normal.

Expect to pay between £15 - £35 for a Bakelite Bellset No. 26, try to get one included with the telephone. Ensure you get the right one!

Coloured Bellset covers are very rare, even the ivory ones - expect to pay a lot for green or red.

Tele's 162 generally came with a plain Bakelite base although some had cast bases painted black. These bases also had a circuit diagram pasted onto them and many were lead weighted. Telephones with a 1/ prefixed to them should have a drawer in the base. The Telephone 232 generally came with a drawer.

Blacks and Ivory telephones at present will cost between £80 - £130 for black, up to £200 - £250 for ivory.

Don't expect perfect transmission quality from them either - but this can be addressed by fitting a modern electronic transmitter - click here for details.

As prices vary all the time do not expect this document to reflect the current market prices for all the telephones mentioned above

Remember - BUYER BEWARE

If you buy on Ebay - go and see it for yourself!!!

Coloured phones will not show any parts that are slightly different colours!

I do not give valuations!
