This was probably used on an older early 1950s 1960s British two stroke lightweight like a Famous James Francis Barnett Greeves? Not sure and your call.

Please take a look at the photos and happy to answer questions or provide more pictures but sold as you see it and no returns. Shipping might be more depending on your location. Thanks
