Ok, I am admitting defeat after several days of searching and not being able to figure out who made this frame. I know there are many on this forum who are much more knowledgeable than me, so I would like to tap into your collective wisdom.

I have looked all over and I was not able to find anything on the web that looks similar to this frame. A brief history. The bike was saved from a garbage truck in Montreal with a complete set of 1973 Campagnolo Nuovo Record components (matching crank and rear derailleur years) except for a Zeus seat post, but it contained absolutely zero manufacturer stickers.

There is one number on the bottom of the bottom bracket, but I am not sure if this is a serial number or a part number (See photo). The only sticker on the bike is the name of the original owner (I believe) before it was placed in the garbage. I have not included the name out of respect because from what I figure out, he passed away about a year ago. The bike itself looked like it had not been used in 30 plus years based on the dust, handlebar tape and cobwebs.

The one possibility is it is a home-made frame by the owner whose name is on the frame. Some of the welding appears to be rather crude.

From what I have figured out, the seat post is a Zeus Gran sport and the diameter is 26.2 mm (There is no size marking, but it seems like all other similar Zeus seat posts have a size marking except this size). This is also what I measured

The bottom bracket is Italian thread (36 X 24F). The rest of the story is in the attached photos.
















I would be grateful for any suggestions people might have. Thanks
