Colnago or something else? Help needed!
 

I've got an id problem with my frame. I have e-mailed to Colnago couple weeks ago but they haven't replied back to me. Can someone help me out with this one. Is this frame Colnago frame or something else? Here are the pics:

I have stripped off the paint and there is Brev. Campagnolo stamps on the dropouts and also on the cable clamps on top of the bottom bracket. There is also Columbus stamps on the tubing. The original paint seems to be red as there was some left in the bottom bracket.

The frame is pretty similar to this one: http://forestbikes.blogspot.com/2008...out-paint.html except the lug cutouts on my frame are slightly different.

I hope someone can help me out.

Thanks!

Taken as a whole, the frame details pretty overwhelmingly suggest that's not a Colnago.

I know that but the bottom bracket is same as on the Colnago Super 1973 which can be found behind the link I posted. I'm also pretty sure that the original color of this frame was red. There is still some left in the tubes. The dropouts are so worn out so I can't tell if there is any number stamped on them which would help with the identification.

I also believe that this frame was made in the 70's.

I'm aware of that. I just don't think the bottom bracket is enough to suggest that's a Colnago when many of the other significant frame details suggest that it's not - the lug shape, cutouts, shape of the seat stay top eyes, the braze-on cable guides (though these could have been added with a repaint) - those are different from every 70's Colnago I've seen (and I've seen a lot).

Can't get the pic working but how about these cable guides?

There is also information about 1972 Super that says this:

COLNAGO on down tube
Fork tangs with two holes
Cable guide braze-ons top of bottom bracket shell
Water bottle braze-ons on downtube

Not saying that my frame is a Colnago frame but I want to know what it is.

Incidentally, the Colnago you linked to is probably later than 1973, though not by much.

Colnago would have brazed the top tube cable guides on the upper side of the top tube and not below.
A 1972 or 73 Super would have had club cutouts in each of the lugs.

Referring to the bottom bracket shape could this frame be made by Colnago to some other brand?

some other brand: the "stem" on that club/clover/flower is not what Ernesto used, even on the "bargain" brands like Colner. There were several Belgian-based frames that mimicked Colnagos, Cornello was a brand you see occasionally, but they also had a different "stem" on their club to this one.
What's the BB threading and the seatpost diameter?

BB threading is Italian and seatpost diameter seems to be 27. The clover is similar to the old Colnago clover which I believe was used in the 70's. Clover on the bottom bracket is exactly same as on the Colnago Super 1973 which you can find behind the link on my first post.

well, I stand corrected, but it still doesn't explain the odd lugs...I wonder if there could be a "Losa" connection?
BTW, that Blog has at least one glaring mistake: Ernesto was a famous team mechanic, he may have once tried his hand at brazing a little bit, but by the time his frames were for sale it was not his hand on the torch that made them: he had professionals doing that, he stuck with marketing the products.

Actually those cutouts seems like the ones in Losa frames but the bottom bracket clover is still haunting me.

Strong rumor (maybe stronger than rumor) has it that Losa was one of the builders that Colnago employed...could be that he used one of the BB shells intended for a Colnago on one of this own. Wouldn't be the first time something like that happened.

I just send e-mail to Losa and once again also to Colnago. I hope they can give me some more information on this case. I really want to know the brand behind the frame.

Finally got an answer from Colnago. They said that it's not a Colnago but they didn't have any clue which frame it could be. Haven't got any answer from Losa yet. So the frame is still mystery. I truly think that the frame is Italian made since the threadings are Italian and dropouts are made by Campagnolo. Frame weights 1.9 kilos if that helps.
