Help to identify vintage road bicycle!!!
Recently I found a vintage bicycle!!I tried to identify the frame maker but I couldn’t.I think many parts are replaced and under the blue paint there is still small bits of gold colour seems to be the original. The is also a 4 digit serial number(4061)on top of the crank. Thank you for your help!!

We need a sticky - something like "How to get help identifying a bike."
For the poster, and possibly such a sticky:
a) photos, drive side first (can't post? 1) get 9 more posts or 2) make a pdf of your jpg and attach that or 3) link elsewhere.)
b) serial number - look under the bottom bracket, top of the seat tube, both side of both rear dropouts - and anywhere else you see a number. Lugs often have 2-digit angles stamped, BB shells sometimes have two-digit frame size stamped. Angles might help a bit, size probably not much.
c) seat tube *inside and outside* diameter - measure the *tube* with a caliper if possible (multiple orientations if the tube is at all out-of-round. The number stamped on the seatpost may not be correct.
d) how you came by the bike and what you already know/suspect about it - including country/city/bike shop where it was originally bought, if you know that.
e) any other information not visible from photos - decals (any small print?), markings/type/brand on equipment...
f) PHOTOS, DRIVE SIDE FIRST.

Sounds like a French bike with a few replacement parts. Looking forward to the pictures!

Thanks very much for the pic assist.
Looks like she has had a rough life; could certainly use some rescuing...
Lug pattern is Prugnat 62/d.
Serial placement is one employed by Cilo of CH (do not wish to assert an ID).
Appears fork not original. Wonder which, if any, fittings are...

Thank you so much for the help !!! I ve been told that some in the past had a crash and the rear fork is a bit bent from the drive side maybe the front fork was damaged and replaced !!! They bought it second hand in 1981 the colour was red. It also had alloy wheels and tubular tyres but I don’t know if they were fitted afterwards!!!

The key parameters include the seat tube outer diameter (hard metric 28.0mm for French, 28.6 for most of the rest of the world), seat tube inner diameter (27.2mm with a 28.6 OD or 26.6 with a 28.0 is a good sign), BB shell width (not reliable, but 70mm tends to be Italian), BB threading (again unreliable, but 36x24 tends to be Italian). Serial number patterns sometimes help narrow down the field, as do lug geometries, as mentioned above.

what is the light grey object at the front of the bottom bracket shell?
cycle appears it may have been fitted with MAFAC brakes at one time
do you have a means of measuring the inside diameter of the seat tube?
do you know the thread of the bottom bracket shell?
bottom bracket assembly appears to have been made up of mixed bits yet crank arms are in perfect registration
here are images of Cilo serial numbers:

Seat tube outer 28,7 and inner 26,3.BB shell width 70 diameter 41,5 out 34,4 inside.Serial number is 4 digits placed weird.The welding on the BB i think is strange.

thank you for the additional information and photos
the combinaton of a 70mm shell with a three-dog fixed cup tells us we are in Italy
the cupset appears it may be OMG brand, spindle is from another maker which is why we saw all of those threads showing in assembled image, the A-8 marking is suggestive of Britain, does anyone recognize the _ASTMAN name?
pillar size suggests a quality plain gauge tubeset
---
frame bits -
bottom bracket shell appears to be Agrati item nr. 000.8507
dropouts are Agrati item nr. 000.8002
bridges are likely Agrati as well but do not have stock numbers for them
one maker who combined Prugnat 62/d lugs with some Agrati bits was Rizzato
however, serial placement is wrong for a Rizzato product
the uneveness of the marking makes one wonder if it may have been made post-manufacture, perhaps put in by a licensing agency for example
one check you could make is to remove the paint from the drive side of the seat tube about five or six cms below the seat lug. if cycle a Rizzato product a number will appear:
in serials of this pattern the first two characters indicate the year of manufacture

That weld on the BB... my old Eaton's Glider had the same mysterious bead that turned out to be brass brazed on. I took it off hoping someone had tried to conceal a serial number but nothing was under it not even a seam. I am super curious as to what that's about and now that I see the same on a completely different style of bike I am even more intrigued. Can anyone shed light on this?

thanks very much Brent!
an Indian origin fits right in with the Brit style model marking
the A-8 model may have been made for use with the 76mm shell. this would explain all of those exposed threads on the adjustable cup.
a new name for me

this web site is a wonderful resource for understanding how frame building bits are made and their technology history. there is a section specifically on bottom bracket shells of the pre-investment cast era. explore a bit...

I tend to doubt there's anything weird with the welding on the BB shell, this looks totally typical of a common welded BB shell. You might see no signs in the interior of the shell cause it's a tight thin line (obscured with threading and dirt) where the exterior was ground with a "V" groove and filled with very visible weld metal. No idea who made this frame (probable non-original fork) but juvela seems to be hot on the trail! If that runs cold then MauriceMoss would be the next best sleuth to take it on.
