I've been trying to identify this Bianchi track frame - any help would be appreciated! Closest I've come is Eco Pista from early 80s, but I'm absolutely no expert on the matter.
The numbers on the BB shell, as far as I can read are: H817 stamped on right, BG in centre, 56 575 stamped on left.
Dropouts are Campagnolo.
I resprayed frame from it's original terrible condition (was Bianchi green with Bianchi decals, not certain though if these were original or not), and put on drilled forks (forks I got with the frame were chrome and not drilled).
