I'm pretty sure I've run into one of the players designed to play those records; it was frustrating, as you couldn't play other records on them owing to the extra spindle. Anyone know more about this ridiculous technological sidelight?

Sears/Silvertone marketed disc cutters in that era, and I have wondered 
if the hole would have mated with drive pins -- I've never measured 
them.  If that is all that was marketed with an extra pin for the 
Silvertones, they would all have had retractable pins.  Even the early 
Zonophones had retractable pins.  The only ones that didn't were the 
Busy Bees.
