Here are some additional photos
sorry about the quality of the rear dropouts

thank you for the further imagery

the specific contour of the domed stay ends when combined with the dropouts is suggestive of an asian origin for the frame

when you had it in bare metal in preparation for the respray it may have been possible to read one or more tubing markings, such as at the front of the chainstays for example

if asian, tubeset would likely be either Ishiwata or Tange

an Ishiwata tubeset would leave open the possibility of a Belgian origin as well

Unfortunately, there were no markings or inscriptions.
I can send you more photos, just tell me which ones.

with respect to originalness of fork -

ends appear they may be Campag

there should be a name legible on their flat faces
markings are sometimes reduced in legibility when fork is polished in preparation for plating

dropouts appear asian so if fork ends Campag that would represent a mixed set

you could check brake reaches
frame appears late enough that it would have been constructed with the same reaches front and rear

mount some 700 size wheels and take measurements
would expect 47mm front and rear, certainly no larger than 52mm

if front and rear measurements differ that would be evidence suggesting that fork not original

---

you mention searching online for a similar/matching frame without success

one thing to keep in mind as you do this is to remember that since frame came to you with a respray the presentation of braze-ons cannot be counted on to be original

you mention that some of what appears to be the original finish was present below the respray
if there was original paint colour on/around a braze-on then it would be original

Thank you very much for your help, I will try everything on in a few days.
Look at the similar frame I found.
Everything is identical to mine, there is even a place to hang a chain.
tommasini bikes
This is the closest I have seen so far.

good detective work - you've really been busy

note how the stay ends of both the grey and the red Tommasini exhibit a "chisel" type of treatment, this is a nicer way of doing it than the plain domed ends of your frame, it takes more work and adds to production cost

the chainstay housing stop on the Tommasinis is a Campag Nr. 621, or replica thereof


the chainstay stop on your frame is clearly of a different pattern

the openings in the top tube for the rear brake cable on the Tommasinis exhibit a 3D grommet which rises above the surface of the tube

the openings on your frame lack an external grommet

Thank you, you are really a pro
Could it be a Koga? Similar frames.

was wondering this as well

if a Koga it would be likely constructed with Ishiwata

they were the first european producer to employ it, beginning 1973
