Amal Grand Prix Racing Carbs-

Just found these Amal T10GP2 1 5/32" Racing Carburetors. Got a killer deal on them from a dude in Texas who received them as payment for helping a "big Triumph dealer" from the 50's move his shop- Big D maybe? He said he didn't know much about them, other than they they were very expensive in the 50's. One pair came with some very interesting spigot/clamp adapters that are cast with Amal part number 376/156. I'm on the hunt for a 510 "matchbox" float bowl, or any other remote floatbowl that will work with these carbs. Also, I would be happy to trade a pair of these GP2 carbs for a nice pair of Amal TT carbs (10TT9 would be ideal) if anyone has any.
