1912 muffler
It helps in this hobby if you know good people who can help you out with good parts.
I got this original front muffler casting from Mark Masa along with the outer casing, the spring clip and the inner pipe. I then contacted Tim Thoele who makes complete repro mufflers for early Harley and Yale motorcycles and he supplied the missing rear casting. All I need now is the centre rod and I have the complete system.
