MAC Racer

Riding around, I chanced upon a motorcycling bar I didn't know about. The location was Sipoo, near Helsinki. I know my Velocettes – as a teenager I bought a 1951 MAC from an old timer, with intention to restore it. It would've been too expensive and I sold it to an older guy. Now this bike's engine says MAC but it looks like a racer. The front fork and brake are quite modern. Could be a privateer's self-tuned bike from the 50s. No one around knew nothing about it.
