Older road bike ID help?

Was given this to rebuild. Parts are all shimano 600, 6 speed, non indexed. Wheels 27 * 1 1/4 (630 ERD). Any guess on what the frame is? Been repainted. No logos. No serial number. Welds/joints are well made and unique. Bike is in Canada so maybe a cnd brand?
Bike is 58cm by 58cm, and the parts look all original and matching, so that should put it early 80's?

Italian. These lugs, the brand escapes my mind at the moment, were used by a number of brands over the decades. I have a bike from the early 50's that uses them. The head tube probably has or had holes for a head badge. The displacement and configuration of those holes may help.

More than likely mid 60's Olmo. The serial format and lugs match. If yours has two vertical holes for the head badge (per repechage's request) that will also support.

I have a 61' or 62'. There were three models. Some here may be able to help further ID the tubing to determine if low or high model but all the N's on the site are the low model (which I also have). Mine is #630k, I did a cleanup up and soft restore thread on it which is linked on Peters site. Olmo Serial Number Registry Peter likes to be contacted so he can add to registry.

Also post a picture of the dropouts, that will help ID if high or low model.

Yep, Italian, specifically Emilio Bozzi lugs of this pattern sometimes also called "Garlatti" lugs since they were frequently used with that make...they may have been copied by another Italian lug-maker, too, there seem to be several variations:
VeloBase.com - View Single Frame Part
But this bike has a Shimano BB so either it's IT threading (probable) or somebody has done something unusual down there.
It's definitely more like a '60s (possibly '70s) rather than an '80s frame...somebody cared enough to give it good paint and a nice Shimano gruppo.
And as for "no serial number", what's that N 5XX stamped right there on the seat lug? Somebody may nail it based on that number sequence, but I cannot.

Absolutely... the rear dropouts will confirm if that's a bottom level or mid level Olmo frame, and then one expects its Falck tubing to be similar in quality.

That is the Olmo Special, not the high end but cool in its own right and Italian. Plus it's older so it's not a boom bike.

The bike boom hit in the early 1970's. It seems everyone and his brother was selling bikes - partially due to uncertainties about oil, partly because Baby Boomers who had reached adulthood saw bikes as something that they could ride as adults. The number of retailers and bike sales went through the roof.

Your bike was made before all that started.

Frame constructed of Agrati "BRIANZA" lugset nr. 000.8030/U.

Upper head lug nr. 000.8034.

Lower head lug nr. 000.8033.

Seat lug nr. 022.8039.

Crown nr. 000.8038.

Fork ends nr. 000.810.

Olmo built with this set and also the Agrati "AM" set, nr. 000.8040/U, up to about the mid-'60's and then continued with the "AM" set well into the mid-'70's.

------------

Appears only remaining fittings from original machine are the Ambrosio steel Champion stem and possibly the Ambrosio Champion alloy bar.
