A good day today, had a couple of hours down in the lockup, stripped the B40 of its front end, swing arm and wheels. Set the TriBSA up on the stand and pulled the Yamaha back wheel off and put it in the Ebay pile. Fitted the Montesa rear wheel in the BSA swingarm, the spindle is too narrow so I'll have to take a run over to my mate Colin's workshop where I keep my lathe and turn ap a couple of adapters and a spacer. The Ceriani front end c/w matching front Montesa wheel was an easy swap I will need to make up a 3/4" spacer to take up the extra spindle length in the yokes but other than that the jobs a goodun!
