I have never managed or indeed wanted to collect all the Special Range Telephones. The decorator phones, sometimes called the Romantic Collection are the sort of telephone you either love or consider the height of kitsch. I tend towards the latter. But here are some images of the other telephones as shown on Rob Freshwater’s excellent website at https://www.britishtelephones.com
The Ericofon 600 and 700 were also part of the Special Range Telephones, but have already been covered here.
