Hi Again,

Further research shows that the 10:1 vernier dial was the PW-D and the other 
2 versions were the NPW-O wiich had the gear mechanism parallel to the dial 
and the PW-O which had the gear drive perpendicular to the panel. The PW-D 
version had the reduction built into the dial and there was nothing behind the 
panel. The shaft size was 5/16". There were many other variations, some of which 
had capacitors attached. These were the PW and NPW series.

Hope this helps.
