I'm looking at buying some of the 'new' DMM brass offsets which I thought were essentially copies of the old HB nuts.
I already have HB offset nos. 2 and 4 and don't want the really small ones (DMM 0 and 1) so thought I could just buy nos. 3, 5 and 6 but I've measured my old 2 and 4 and the sizes don't match up to those given in size charts for the DMM nuts.
For example the DMM 4 is given as 7.5x10.2mm but my HB nut is approx 8.2x9.6 which is quite different.
Did DMM change the sizes? I can't find an old HB size chart for comparison.
Thanks.
