Vintage slip-on chamber from Sito. Right side mount.
This one is a lot larger than most. We think it might be for a shifter bike. There is a small bit of the seam removed where a foot brake might go. Maybe this would work on a Cimatti 86 or similar?
Vintage and old. In good shape but small amounts of bubbling paint in a couple areas, a little rust in spots, even a small ding. This things older than the internet so that's expected.
Overall length is 31 inches.
The clamp is 32mm with a little wiggle room there so check your stock header.
