While going the parts boxes for a manifold for my 21F project, I discovered I had three types, as illustrated in the photo.
A. appears to be a bronze casting, with no casting identification marks, and nickel plated.
B. is a steel casting, with a "button" style id mark on the right hand leg as photographed, and nickel plated.
C. is also a steel casting, parkerized, and with the linked HB or BD marking on the top centre. (I've re-blackened it, hence the new finish.)
They are all dimensionally similar, though Type C is less delicate than the others.
Two questions: I assume that type C is correct for my 21; am I correct? And for what years/models are the others correct?
