Nice muffler. I see the package is open. Did you check to see if it also fits the OS 61? I just bought a 61 and want to make sure it will fit. Maybe the muffler was made before the 61 came out?

The Muffler fits the O.S 50/60/61 FSR Engines. Does not fit O.S 61SF/FX or 65AX

I have about a half of dozen of these Mufflers on my vintage pattern planes. They look really nice when you polish them up.

Wow they really do clean up nice, just beautiful. I think Kavan? advertised the flow through design did not adversely affect engine output. A huge plus in itself I think.
