Telephone 275A mk2
Has anyone seen/have any knowledge of the above test phone please? I have seen a photograph of one, which appears to be a 705 linesman's phone with a few extra switch panels added. Is this an official model, or a home-brewed job?

I can find no reference to such a Telephone 275 in my copies of the GPO/PO's 'Vocabulary of Engineering Stores' or my thousands of 'N' diagrams. Nor have I ever come across one in my 50+ years in telecoms. There is what at first glance looks like a Tele 704 but on closer examination it is a Tester used with PCM - can't remember the number or find the one in the loft . Where is the information that it is a Tele 275A found? Where can the photo be found? Ian |

Re: Telephone 275A mk2
It looks to me like the modifications were done professionally but by whom and to what end is a mystery.

Re: Telephone 275A mk2
Thanks Ian. Sorry, 704 is what I meant, finger trouble again! Photo is on eBay. Looks like a modified set to me, but seems to have been well done.
