There's an interesting older Bianchi track bike on our Finnish online auction site.
The seller claims it is from1940s or 1950s and that "it has been raced on the track at national level" and comes with two pairs of wheels, the other with wooden rims. It will be a cool project for someone and as far as I can see it looks to be quite similar to the nice restored one I posted here earlier.
Tnts managed to extract what appears to be correct sizing info from the seller and it's obviously way too big for me. Frankly I'm relieved. But here's some more photos:
