Write him a LETTER -- yes - you know the kind- piece of paper, pen, write words on the paper to the effect asking what you want and in a short time he will write back. This might sound "glib" but he IS a busy man and has no time to stop what he is doing and answer the phone. I wrote him a letter asking for barrel work and within two weeks I got a reply along with a list of all his services - no fuss - no muss and no miss-understands.
I understand that he moved his shop(?) and I don't know if this is his new address or his old one but someone here can let you know which one it is - good luck. The Freischutz Shop 2379 Mount Hope Rd. Fairfield, PA 17320.
