 If you are still looking, check this out: http://www.ebay.com/itm/BSA-A-10-Inner-Primary-NOS-/262363758165?hash=item3d16193e55:g:GK4AAOSwYHxWNoED&vxp=mtr

 I hope I did that right.

 Mine was cracked, and twisted out of flat 3/8 of an inch. I flattened it out, welded it up, and generally did everything I could to try and save it. But in the end, the twist became a double twist and the only way to get a flat mating surface was to take a skim on the mill. This would have been almost 1/4 inch DOC to get it entirely flat (little more that a "skim" ).

 I bought one of these NOS covers from this guy, and it really is NOS, really is perfect, and shows exactly how BSA polished cases. I have no idea where he got them, or how many he has.

  Y' never know, someone may have figured how to do a quick sprocket change

If you cant find one closer, I've got about half a dozen spare, none mint but most serviceable
