Possible Geoffry Butler Frame

mike1251

Retro Newbie
I picked this up to add to my collection and restore, can anyone identify the period of the frame by the rear brake bracket or the bracket on the chainstays, also the the stamped number on the BB is SL6 2YT 3 . also the cable guide under the BB was made in france and fixed with some type of silicon/glue. The groupset is shimano exage 500lx, the bars have engraved Dawes handbuilt in England so Im guessingthis is a mismatch of parts?
many thanks

the frame's two plate style bridges betray it as a bottom ender something or other; quite possible they may both be Agrati items; the Pletscher plate style bridges are marked with the Pletshcer name and the Agrati ones usually not marked

fork crown is Agrati pattern Nr. 005.8028 which is part of the Agrati "ROMA" lug ensemble ART. 000.8020/E/U

tubing set likely to be hi-tensile, a check of saddle pillar diameter will be a helpful clue in this regard

recommend investing no treasure in this iron

if frame of British origin one possible maker might be the Coventry Eagle/Falcon entity

during the period of Mr. Ernest Clements residence the firm employed a fair amount of Agrati bits in its frame construction

there is also the possibility it may be of Italian origin

one simple check would be to determine the thread of the bottom bracket shell

I've been doing a bit of investigating, as I'm going to strip it back, it has a frame number 269549 on left dropout, also has 72 stamped on the headtube just below the top tube. A seat post diameter of 26.8ish as measured with a vernier guage. I also thought id weigh the frame and forks fully stripped of components frame is 2.18 kg or 4.12lb the forks 842g or 1.13lb. The paint looked original though
 
Hopefully someone will be able to help with the number on the dropout. 72 on the head tube is the headtube angle 72° 👍

Personally, I wouldn’t strip this frame. The original paint looks perfectly serviceable and there’s nothing wrong with a few scabs. In fact, the paint on that is better than on both my ‘best’ bikes. I’d just clean it up and use it as a nice little bike you don’t need to worry about!
