MG T type I think, TC or TD, though they look a bit big. What diameter are they?
Possibly from the Big 4 Riley engine, used in several 1940s and 50s models until the dreaded BMC swept Riley away.
Something else I didn't know, or forgot!Apparently the later TD's (MkII and up) used 1.5" carbs, I will bet that the TF's did too
