Wow... the more I read this the luckier I feel...
Now... the Leica body I got from him turned out to be defective. I called him and he told me to send it to Don Goldberg, in DAG. I did, and DAG billed Chatterton; however, the problem didn't disappear and I sent the camera again to DAG, and came back the same, so I...
To make a long story short, DAG couldn't fix it, and I'll eventually send the camera to Dan Elwell, in Leica NJ, to have it refurbished. Right now, ever since its last visit to WI, my camera has produced only one bad exposure. Go figure!!
A final note: the last time I spoke to Don Chatterton about the camera, he offered to buy it back from me (the warranty had expired, this was after the second visit to DAG). Now... I never took up his word on that one because I had grown attached to the camera. Am I weird?

Probably... but lucky too!
merciful, the best thing you can do is call Don early in the morning. I believe you're on the Eastern area, so call him at YOUR 8 AM. It'll be his 5 or 6 AM... and he'll answer the phone for sure!

Again, best wishes and good luck!!
