Hi, I bought this to use as parts to update my 60s Flandria that is falling apart but after using it for a while it's far to good to mess with! I have tried doing research and spent many hours staring at Google images, to no avail but hope someone out there will put me right!

Clues:

8971 (consistent with Chas Roberts numbering but I can't find anything like it?)

Cast Reynolds BB with brazed on cable guides
735 on top of Seat Tube (assume the angle)
Campanolo dropouts (stamped)
Sweet rear brake cable routing in top tube (like Pinarello?) where you only thread the inner.
Dainty diamonds on brake bridge and bottle lugs
Seat tube 27.2mm
The BB is 68mm wide and the Hollowtech I removed is a 37 x24, so English
Removed the forks, they also have Campo dropouts the fork Steerer tube is 1" Diameter with no other markings?

All in weighs 8kg without the Bag!

Grateful for any advice or suggestions

Thanks
