Our catalog record shows it appearing in gear cluster listings from 1969 to 1970. If you're rebuilding a gearbox and checking clearances, this is one of the shim-style washers you'd use to dial in the right amount of float.
The manufacturer tag on this one says BSA, but nothing else in our record points to a specific model. If you're not sure this is the right thickness for your box, measure what's coming out before you order a replacement.
