There is no doubt that the 1S in .218 Bee is not as rare as some believe. Maybe the entire production of 600 for Sloan's is the extent of production, but I tend to believe there were more than that made over a several year period. My own 1S Bee is in the 133-59XXX range. They are known with both red and black pads.
I feel it is a matter of demand and interest for this caliber/configuration that makes them relatively scarce, rather than number produced.
