The sticker looks like the SL sticker from befor3 they put SL on them. What size is the seat post?

Some good pics of the whole bike and some of the frame details would help a lot. Form the limited pics all we can really tell is it's a better quality SL tubed frame from the late 70's early 80's.

Tried to find info on VGL and came up empty. Probably a boutique builder. In any case it looks very nicely made with good tubing, thinned window lugs, etc.

The Columbus decal is the SL version issued 1978-1987. From what I can of the bicycle, this looks reasonable. You can narrow that down somewhat, if the bicycle has Campagnolo dropouts, by determining i fthey are the Portacatena version.
However, a 26.6mm post is 0.6mm smaller than one would typically see on an SL frameset. The cinch slot doesn't look pinched. 26.6mm is more indicative of Zeta, Aelle or one of the Tange tubesets. Given the discrepancies, I'd want to see this one in person and verify the post size, then check the fork steerer tube to determine if it has the five helical ridges indicative of a Columbus steerer, which is usually a good indicator that the frame is at least SL grade.

The seatpost clamp and fastback seatstays remind me of what's on my 1984 Gitane Tour de France........
Stronglight headset and JPR seatpost??......Hmmmmm.......Maybe its Swiss??

Good point Chombi1! It might be the metric version of the Columbus SL tubeset. That would explain the seat post size in conjunction with the Columbus steerer tube. It's easy enough to verify, by measuring the outside diameter of the seat tube, which would be 28.0mm, as opposed to the 28.6mm on the imperial standard tubeset.
BB shell without flying-C logo or spoiler suggests very late 1970s to very early 1980s, which matches well with the seat post date code.

and the stripes are four colours (blue, red, black and yellow) not five
