Is this a messed up Akro corkscrew? About .9 inches.

An Akro that didn’t spin properly IMHO.

Akro patch. And it's not a matter whether it spun properly rather, The Barker system and spinning cup was designed to vary from patches (no spin) and all the way up to about 2-1/2 spins all at the same time while the system was running. Not only that but because it used a friction gear which enabled this range of variation. , In fact I have an original 1928 100 count box and it contains a patch and 2-1/2 spin in it. In my box, it seems the odds are 1 in 100 to get 1 patch and the same 1 in 100 to get one 2-1/2 spin. All the rest vary in the number of spins each have.
