What is this? Very close to a 1981 Trek 710 but isn't.


While hunting down parts for another resto-mod project, I came across an old frame.

A local fellow's father had found the whole bike at the side of the road during cleanup week brought it home to his son.

The son disassembled the bike, cleaned it all up, stripped the paint, clearcoated it, and rode it for a few months.

He needed money for repairs to his mountain bike, and decided to part out the curbside find. I saw his ad on pink bike and was interested in some of the components. I met him at a donut shop, and purchased the frame and fork, with a Phil Wood bottom bracket, a Sugino AT triple crankset, a 600 Arabesque downtube shifter set, an SR Laprade seat post, a Campy headset, and front and rear Blackburn racks for $120 CAD.

Now, I am going insane trying to identify this frameset. The previous owner thought it could be a Masi. I thought it was a Trek 710. I have asked around, and my latest lead is that my “go to” LBS owner thinks it could be a Falcon or some other British bike.

The details I have are as follows:
Center of bb to seat post binder bolt 54.5CM
Center of head tube to center of seat tube 54CM
Center of bb to center of head tube 62CM
Center of rear dropout to center of BB 44.8CM
Seat stays 54CM
Drop out to brake bridge 36.5CM

The gas exhaust hole on the left fork is on the outside.(manufacturing mistake likely?)

Haden Europa fork crown

Shimano sf dropouts

It has Reynolds Butted stamped on most of the tubes. seat, top, down, and steer

It has 140 11 82 stamped on the chain stays
(Ran out of allowed attachments, see web directory of bike being stripped"

Bottom bracket is stamped with EO in a diamond

I think it is very similar to a 1981 Trek 710
Its bottom bracket is shaped like a trek bottom bracket
The BB cable guides look like Campy over the BB guides(like on a trek 710)
But, the chainstay bridge reinforcements are not something Trek used

All lugs and dropout looks like the lugs and dropouts used on a Trek 710
(The Trek uses Nikko Sangyo seamless long point Italian cut lugs)
All cable guides look like the trek guides

Seat stay caps are cast without the name trek

It does not have rack mounts like a trek 710 would have
The brake bridge and chainstay bridge reinforcements are not something Trek used

The serial number is completely wrong for a Trek
It is 424769

The rest of the photos of the bike being stripped are here:

Sorry for the long post, but any help would be appreciated.
