Tired Wheel Deal V: Mondia Super (frame only)

Don't be fooled by the name on the seat tube. Perhaps the previous owner's name was Giovanni, or something. In any case, it's been repainted, and was hard to tell what the frame truly was. Can you figure out the giveaway?

If you guessed the bottom bracket threading, give yourself a gold anodized track cog. Swiss bikes used french thread pitch with reverse threading on the drive-side cup. Here is more info on Mondia bikes.
