Hi everyone,

I recently aquired this frame from a good friend, who bought it a couple years back from some store. The frame had a very nice fork with a double-plate fork crown, but unfortunately it was bent in a crash, as were the top and down tubes (though just a little).













The following images show the serial number, which is stamped on the left side of the seat tube under the seat cluster — 6094. And a number stamped on the bottom bracket shell — 25.





It looks like the head tube lugs and ends were chromed:





I'm going to have a local shop owner (oldtimer) with experience in repairing frames replace the two tubes to make it rideable again. He's also got an old track fork with a straight crown lying around somewhere (or so he says) which I will hopefully be buying from him.

Anyway, no one's been able to tell me or even give me guess as to the make of the frame. The shop owner said it probably dates from the 50's or 60's because of the ends, which he said were stamped rather than forged (?) like modern ends.

The frame originally had a badge, judging from the two holes on the head tube. Sorry I don't have a picture — I've pointed out where the two holes are in the fourth picture though.

Anyone have any idea what it might be?

Thank you everyone!

Forgot to mention:

Seat post size appears to be 26.2 / 26.4 (Campagnolo NR seatpost pictured is 26.2 and goes in very easily).

Bottom bracket is Italian and sizing is 55 c-c squared.

By the way, what size are the bolts needed for this NR seatpost? Can they be found a hardware store?

Legnano

Just a guess, but that is what popped into my mind

Let's see some images of the fork, and what is the steerer length? I have a major beef Italian pista fork. I am not sure of the steerer length right off hand, from about this period.

Not a Legnano. At least, not a classic one. Seat bolt is on the wrong side.


This is a classic Legnano.

Sadly the fork has been lost — I think the previous owner left at the shop, since it was all bent. I think we may have been able to salvage the crown, but who knows? I'll measure the head tube as soon as I get a chance.

Any more guesses?

Thanks everyone.

Looking through the Italian marques on Classic Rendezvous, I came across pictures of an old Bianchi with very similar lugs — https://www.classicrendezvous.com/Ita...51_g-apple.htm

The chainstays also look similar.

Most Legnanos of that period put the seat clamp under the top tube in front of the seat tube:

Several of the 50's bikes on CR had very similar lugs. I guess many of them used the same type. A Bianchi would probably have Campagnolo track ends, and were it from that period probably also the "Bianchi headset" —
