Chasing down a correct carb for one of Mark Sheppard's Thruxtons

The Blue/Silver Thruxton with fairing, of Mark Sheppard here at the shop for service, had an Amal Mk2 carb, but originally came with a Amal GP. Mark asked if I could chase him up a correct carb set for the bike. I was able to locate and purchase a correct Amal 1 3/8" T5GP2 carb from my long time customer friend Rick Price back on the East Coast, then located a correct NOS Amal 510 remote float unit from BritCycle in Australia. Next is to find a correct cast alloy finned inlet manifold . Also locate a correct carb bottom fuel inlet fitting with a single fuel hose spigot, and fabricate up a float mounting set.
