Late type pre-unit BSA, A7, A10, B31, B33, DBD 34, Gold Star etc. primary chain case. Has been bead blasted at some stage. Marks inside front dome from a loose engine sprocket nut as they often have. All threads ok. Pock marked from previous surface corrosion so won’t make a concours de elegance finish but ok for scrambling or if you prefer a more life lived desert sled look for your build. Been on the shelf in workshop for many years, hopefully useful to someone?
This product would be a great fit for collectors or anyone interested in vintage primary chain cases.
