I am not trying to hijack this thread but I accidentally slipped into the 41Magnum Cult today with the purchase of a M57 number N707XXX and would appreciate it if any of you kind folks could give me any information about it such as date of manufacture. It has a pinned barrel and recessed chambers. The previous owner had rubber Pachmayr grips on it.

I have been shooting S&W revolvers from .22 to .44 Magnum for over 40 years but have never had any contact with a M57 until today.
