I couple of weeks ago I decided to replace my M15 (steel shot) cb. I had been having trouble with it for years, although until the discussion on the M-site started, I didn't understand the significance of the steel shot problem. Anyway, I contacted Bob,and sent him a check. He delivered the new cb to the shipper the same day, and I got it a few days later. Bob was very helpful, both by e-mail and in the phone conversations we had. A pleasure doing busines with him. Now all I have to do is put it in. Don M15-248
