Hi again Gizzy,
I told you of Albion content in the "Motor Cycle Repair and Upkeep" series published by Newnes and that it sometimes appeared on eBay. Someone must have been listening as a couple of copies are on EBay at the moment. Both the full set of three volumes and the odd singleton volume. The full set is worth the bother if you are seriously in to late vintage motorcycles.
Cheers,
