The dial on the left is a 522 and the one on the right 536

The 536 and 522 could both go on a 992B, but the 522 would be the only one correct for a 992E of the two dials?

Yeesh...

That's right Jon. Actually the DS BM Numerical dial (Dial 522) would be correct only on early 992B's. Later on it would be supplanted by the DS BM Numerical RWS dial (Dial 537) (see picture).


DS BM Numerical RWS dial (Dial 537)

Ed,

Ok... This is almost starting to make sense.

Thanks,

Jon
