Hello Mr. Old, well the data was coming in so well and then I got the last one that threw my whole theory out of wack. I thought that maybe one time there would be a nice clean break between nickel and blue controls.
Nope, S&W did not waste any parts, just mixed them in together. But Im
narrowing in on a period and Sn. range that the switch occurred. Im
still taking data and recording. Mike

Mike;
Just picked one up this weekend. Didn't even think about the blue parts until I saw your post. Anyway;
A3296XX: blue safety, slide release, plate on frame below safety and trigger pin.
Silver box with matching serial number.
I hope that this helps;
Mike

I just rec. a list of 11 nickel 39-2s. He forgot to note the controls in the mail. When he sends me the revision list I will add the controls.
Meanwhile I will add his 11 to the list.
