Hi sixthwisconsin.....welcome to TFF.
The only website that I know of that used to
have that kind of info was the Springfield Research Service: http://armscollectors.com/srs.htm
.....but that website seems to be out of service now.
The only thing I can think of is to contact John Spangler or Marc Wade from the Arms Collector Website and see if they have any suggestions as to where you can find the info you want.....
It's a real bummer that the SRS is closed down.....it sure was
a valuable resource.
