I recently purchased new primer slides (large and small) and many other parts from Bill Cunningham. As Bill is in and out frequently, I have found that it is best to send him a letter with my order versus attempts on the phone. I provide my email address and he responds in time with an acknowledgement and cost for the parts and shipping....which I pay by USPS money order. You can visit the Star Machine Works website to see the part lists....but the prices are out of date.
