Identify these Weaver Pivot Mounts

Gunswapper

I have some New Old Stock Weaver Pivot Mounts I have been unable to find in my catalogs. These are in old manilla envelopes with green borders and writing. These are marked "BASE NO. 120" and "BASE NO. 148". Both are also marked 'for WEAVER PIVOT MOUNT". Can anyone tell me what rifles they fit and are they front or rear bases? I can add pictures if neccessary. Thanks in advance.

120 is a weatherby mark V Front

148 is a rear Winchester Model 70 or 54


according to the ones I have packaged

The 1 in 148 designates that it's a pivot mount the 48 is the number of the conventional base for that model rifle . Usually you can go to the Weaver catalog , and solve the riddle very quickly !
