Classic frame identification- Help needed

Hello,

Couple years ago I bought pretty old race bike, I was riding it by 3-4 years as daily driver. Then, after new bike purchase, I have left it in the basement for 2 years.
Recently, I have decided to use it again. I pumped air into wheels... and it was not what i expected, so I thought to clear up some elements, just adjust this and that ... and now, here it is, "clear" frame ready for repaint

My first though was to make custom racer, but after couple looks on my beloved bike, I have decided to try to go back to original paining and decals

Now is the ask for you, the community, could you help me what is the factory of my frame, maybe somebody give me some hint.
What I know:
- Current painting and stickers are not original ones

- Frame has been originally painted light blue metallic.


-Frame lugs are Bocama - probably competition series
- Wheels Mavic - MA2 (rear) MA40 (front) - Shimano hubs
- Components were from many different producers. On Board: Hatta Swan headset, Shimano derailleurs, SR Apex cranks, Sountur Cassette, Cinelli bar, Gia Compe Brakes, etc. Mostly Middle class or low-end.


- Last bout not least - Searial number - it seems to be "267.5.VK80" or it also could be "267.5.YK80" or without dots or any other variation. I've found digits on right side of seat tube and is not drop-forged but possibly handmade engraved . Unfortunately barely seen in the picture.


What I would like to know:
- Who could mark frame like that? any idea/hint/ suspicion would be appreciated.

Thank you in advance for any feedback.

Regards
Cuba L.

Tough one.
Bocama lugs were used by many, these have been modified a small amount, note the reinforcement ring is not present where it would seat the headset.
Some more images of the fittings, drive side dropout, both sides, seat stay caps, bridges, both brake and chainstay, bottom bracket shell both above and below.
The threading specification of the bottom bracket might suggest something.
So far it appears a production frame of ...

Thank you for answer.

I am aware, that Bocama is not a trail, but says, that my frame is for sure not from East Europe. I bought this bike in Poland, and, let say, in 70' and 80' eastern market was pretty hermetic, so we meet mostly ZZR Romet Jaguar or other Favorit.

Bottom Bracket: Width is 68 mm, threads seems to be right and left, so it could be British ISO bottom bracket. I need to check insert for more precise measurements.

UPDATE:

Recently I have removed paint from some places on my bike and look what i've found:


So we have frame with Bocama lugs and Shimano SF dropouts, to make it more difficult front fork is Tange OH, full chrome. Photos below, also better view of Serial Number:


So for me it is probably Japan bike, but could be also Benelux or Austria....or many other...

Another component research: Bottom Bracket insert is made by Nervar, Rear Derailleur is Shimano Z503 84', front is s60 (probably mid 70'), shifters - Shimano LB-100 (also Mid 70").
All of this and Dia Compe G brakes/Cinelli bar/Hattaswan headset/SR apex-5 crankset etc. says to me that somebody just putted into this bike what he found in garage, so chance to decode bike by components is less than 0.

I am still stuck, but if we don't find out what is the frame producer I'll just paint it blue and put some decals, which I find as nice ( maybe Puch?, would rader not to desecrate Ciocc or other Colnago ).

Possibly the Bocama-pattern lugs are mere generic copies that a Japanese factory could have sourced. Or is that a positive brand ID shown stamped?

At what point a Japanese-made bike was brought into Poland would be anyone's guess, barring some info from the previous owner.

What does this bare frame weigh? To be consistent with those Japanese parts it should be well over 2kg.

It's your call as to what paint scheme that you would like to see on it. Having the parts at least credibly matched to the marque/model would be a good start.

Show us a picture of the repainted bike when you get it built!

- BCM on lugs is stamped, and lugs have identification like Bocama, f.e. 72 deg. angle.
- Bike was bought from trader who bring bikes from Germany/France/Benelux in 2010, so no chance to ask him, or expect that he remember anything.

- Frame weight is ca. 2.2 kg

- Yes, well, painting is definitely on me, but i am still looking for some similar bike in old catalogs. Now I think i have no chance to find something equall, but Miyata seems to be proper choice, even if their frames have better details.
Or You may have some advice?
