Don is probably your best bet. You could check with the other big names as well: Youxin, Sherry, Gus, Kindermann, Steve in California, and those dudes in the UK (CRR Luton and ?can't remember?). I happen to have the ss dial you're after, but I have great hopes of putting my M3 back together -- some day soon
I have learned that Don greatly prefers to be called and not emailed. In fact, he once (rather perfunctorily) told me that I should call him and not email him because he cannot work while doing email -- but he can continue to work while on the phone. I think he either uses a speakerphone or a headset. Clearly its of benefit to us all to call instead of email.
So I will always call him from now on. It is interesting to hear that he has so much work he doesn't have time for email
. I don't know if that's good or bad. I'm hoping its good.
I have a couple things to send him....I'm contemplating the "season effect" of shipping things during the bitter cold and icy dead of winter. I might wait until the weather improves and shipping is less dangerous all around.
