FR buttstock stamping question
On another LE forum, the 'FR' buttstock stamping has become a topic of some interest. The reason for the stamping appears to be unknown, subject to much conjecture as to its origin and its intent. Much speculation but no definitive answer. Why so many Savage No.4s are so stamped (but, some SMLEs/No.1s apparently have been similarly stamped). I am speaking solely of the 'FR' stamping on the right side of the buttstock (done in many fonts) and NOT speaking of the RFI 'FR' stamping on the metal of the action body. Questions: What does the 'FR' stamped on the buttstock signify and by whom done? TIA. Old Crow
