You are looking at an old Amal Monobloc Carburettor Body that has a 15/16" diameter inlet and is stamped " 376 / 313 " on the flange. This is listed as being for a Royal Enfield 250cc Crusader and is used with some light wear.

One of several lots of motorcycle parts I am currently selling on ebay.

Please note, all items posted outside of the UK must now be sent via the global shipping program by order of ebay. I no longer have control over the amount charged or the service provided.
