Gil;
Certainly a very nice assortment of roll crimpers you have there, thanks for the pic. I don't have near this many but do have 10, 12 & 16 gauges. My 10 gauge is the best quality one I have, looks somewhat like the one below & to the right of your Red one. I made a 12 gauge head for it patterned after the original 10 gauge & can insert a sleeve for the smaller hulls & have used it for loading 12s as well.
A bit more modern but still obsolete I have picked up Herter model 72 & 390 presses. These are both of heavy cast iron construction & near indestructible.
The 72 I consider a single stage though all dies are set up & one could load a single shell without any changes, however, each step is done individually. When using it I found it more efficient to go through a single step on all cases before going to the next step. The 390 will produce a loaded shell for each pull of the handle but requires more movements of components etc than more modern progressives.
