BSA Shim, engine sprocket (·015"; ·381 mm.)
A .015 in. (.381 mm) shim used at the engine sprocket, per the parts-book listing.
This is a shim used at the engine sprocket, listed at .015 inch (.381 mm). It shows up in the crankcase and cylinder/crankshaft sections of the parts books, which tells us it's a thin spacer used to set up the sprocket position on the crank end, but the catalog entry doesn't spell out which machine it was fitted to.

The manufacturer field on this one points to BSA, but we don't have anything else in our records confirming that beyond the tag itself, so take that as a starting point rather than a certainty. If you're chasing sprocket end-float or lining up a timing-side setup and found this number in your parts book, it's the same shim under the older 40-69 form.
Given how little detail we have to go on, best move is to bring in your parts book or give us a call so we can confirm this is the right shim for your particular crankcase before you order.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
