[GreenKeys] Teleprinter part wanted, can you help?

[Godfrey Manning]

   Dear Sir,
                I'm setting up a dual teleprinter demonstration at home as a hobby. A Teletype ASR-33 awaits attention so as to 
bring it back into working order. I'm also working on Telex equipment, I am running British-made Creed 7 and 444 machines. This is 
in addition to my long-established Friden Flexowriter 1SPD (the one displayed on "Wikipedia"). Is there a source of spares for the 
Teletype or Creed printers? Also a workshop manual for the Creed 7 (both B and E) would be helpful.
   Mr Creed 444 has a snapped tape reader drive belt and so I'm looking for a replacement (or reliable means of joining the broken 
ends of the existing one). There are also other items that would be helpful.
   If it's of interest to anyone, I can help with some technical advice on the Flexowriter and just possibly the odd spare part 
(very limited). I also have a couple of spares available for the Teletype, but again very limited.
                    Many thanks for your help.
