Hi tdgmtx, and a warm welcome to the forum. It's great to have a Scott Bonnar Model 17 'Supercut' owner on board.

Being first introduced in 1950, after 62 years, some spare parts for this model are scarce and some just not available. However, I may be able to help you.
I will send you a PM...(look for a flashing envelope in the top toolbar, next to 'My Stuff')
Once again,

to OutdoorKing.
