Here is a nice original 45 center hole adapter used on the AMI model A,B,C,D,E 40 jukeboxes when they are converted from 78 to 45 rpm. This is an original part that I removed from an "A" model. 

Sold as-pictured, as-is.

Shipping is a flat $5.00 in the USA. Will gladly ship worldwide, with actual International shipping figured for winning bidder.
