Sorry Ted, don’t think you are entirely right there, some post war machines might well have a spacer for all I know but certainly my ’51 registered Shipley DPY 51xx engine’s inlet studs, (originals), are only long enough for the carburettor flange, a gasket, nuts and washers. Certain there is not enough stud length for a 3/4” spacer so maybe this is just a Birmingham thing?.
So, one for one against, any more offers?
