Hi all,
I am embarrassed to post this, however I too would like some help to identify an unknown frame I have bought.
What I do know:
its a 23 inch frame (BB centre to seat pinch bolt centre)
It has no mudguard eyes,
The steerer tube is stamped "reynolds 531 butted 16.13"
It has a "divers helmet" rear gear cable stop - which needs a stepped ferrule; (an Italian feature?)
it has a 3/8 drain hole, tapped UNF thread in the bottom bracket with a plastic plug (UNF == USA?)
The bottom bracket has EO in a diamond stampede in to - the trademark of the Otsuya Iron Works in Japan, I believe
The Frame and forms are both stampede with the number 4701 so I assume they match.
It has Campag dropouts, and the drive side rear is drilled for a Portacaena chain hanger
The seatstays have long scallops
the seat clamp is threaded to take a metric bolt
the bottom bracket is 68mm and BSA threaded
the steerer tube is British threaded
it has brake cable bosses on top of the top tube
downtube gear leaver bosses
A chain hanger boss on the drive side seat stay
it has gear cable bosses on top of the bottom bracket
frame weight 2.1Kg bare but painted (531db, possibly 531c given its size and paint?)
fork weight 725g bare but painted
The seat tube is somewhere between 27.2 and 27.4 - currently I am using 27.2 with a thin shim.
it has a silva 189 brake bridge (a box in the middle of the tube drilled for a large diameter recessed brake nut)
from my investigations I have been told it could be an early Cougar frame from the mid 1980s, though I doubt that given the japanese BB and I think the over BB gear cables dates it more to the 1970s.
I bought it painted and scraping away a little of what is there it seems to have been blasted leaving no trace of its earlier identity.
This is my daily ride and I have no intentions of selling it, I am just very curious as to what it is.
Thanks for any help,
-Steve
