I've always been curious to have a stepper.
Whoever bought that IIIc, they will be happy. Don made my other Barnacks into such nice machines -- even when I just sent them in for a simple little fix. The camera always came back running much smoother and looking much nicer. He just can't let things leave his shop in poor condition if he can help it (or so I imagine).
Times have been tough in my household since late last year, but I'm still going to send Don a couple things to "fix". One is my Tele-Elmar 135/4 with a very slightly sloppy focus ring. Quoted me $155 to tighten it up, which sounds a little steep if it were anyone else, but I know he will also ensure the lens is calibrated to factory standards (for accurate RF focusing) and he will probably address any other little issues he finds without even mentioning it, or charging me. So it becomes a bargain 🙂
