Stopped off at the LPM stall at Stafford to inquire about short style CB750K0 plastic chainguard replicas. A fellow restorer (not on forums) bought a couple and said they were a very good replica. Lady , who was on the stall, is the daughter of the founder but her father has sadly passed away. Evidently it's her brother (separate to LPM's main business) who produces the chain-guard replicas. I will contact him and see if he can still supply them, price & delivery etc.
