Don’t be mislead, when you are looking for vintage telephones in the UK you will see a wide range of prices for British Bakelite telephones. The main two things that impact the prices are the condition of the Bakelite and the mechanical service and restoration that the telephone has received.
The condition of the Bakelite is usually relatively easy to spot, its a lot like pottery where hairline cracks or significant chips above a couple of mm (nibbles) will massively impact the value (up to 95% or the potential value). So the important thing here is not to just rely on the photographs of the vintage telephones but to ask the seller to confirm that there are no hairline cracks. If they are a reputable antique/vintage telephone restorers they will be happy to confirm this. If you buy from an antique centre always make sure you check the Bakelite in a good light, ideally look at the telephone in sunlight.
It is much harder to determine the quality of the mechanical service and internal restoration that the telephone has received. This is one of the main reasons why you will see a big difference in prices from reputable dealers and those on online auctions (or generic antique dealers). If you can’t confirm that this service and calibration has been done correctly your best option is to offer less for the vintage telephone (about 60% less) and then have the telephone serviced elsewhere.
Always do your homework and research, there are some dealers that sell via places like eBay that you really would not want to service your “pride and joy” telephone and that really don’t know what they are doing with these iconic telephones, even though they have been in the “Antiques” business for many years. Research, research, and more research. As always word of mouth is always the best recommendation to get a good vintage telephone restorer.
Although this site is mostly about Retro Telephones I believe its still worth mentioning the classic British 200 series Bakelite Telephone. These antique telephones were the first Bakelite Telephones to be used in the UK. These telephones were made of Bakelite and had a separate “Bell Set” that contained the bell. However, this “Bell Set” could be mounted underneath the telephone as shown below and the telephone was then called a “combined set”. These Bakelite telephones are now regarded as extremely desirable iconic Art Deco phones in the UK (they even work on a modern landline telephone point).
These 200 series telephones were predominantly made in the 1940’s, however they were produced for the GPO between 1929 and 1957. These vintage telephones were produced in the standard black, rare ivory, very rare red and extremely rare jade green.
Again although not classed as Retro I believe its worth mentioning the most popular British Bakelite telephones (classified as Antique or Vintage), known as the 300 series Bakelite telephones.
They were the first British Bakelite phones to contain an internal bell. Before this telephones always had a separate “Bell Set”. This superb telephone with its classic hard lines is very sought after today. The standard 300 series telephone was known as model 332, although the 300 series range contained several models, usually resulting in extra chrome buttons (above the dial). For example, the model 312 had an extra chrome button for shared service working (when telephone lines were shared with another telephone subscriber due to lack of available wires to the local telephone exchange).
The other models with the extra chrome buttons are rarer than the standard 332 and hence they are more collectable and harder to find in “Grade A” condition.
In this Bakelite Telephone Era 99.9% of all these telephones were Black.
The rarest colour for an antique 332 telephone is Green as in the one above.
