John,
Got your email. Here's some of the reasons why this knife is post mid-90's. Assuming the entire combo is original, which I believe is so:
RMK "logo snaps" were not introduced until late 1994-early 95. The inclusive FLA S blade stamp has been around a long time on 1/4" stock knives. Lastly: Scott Maynard shaped and finished Model #1's from the 1980's well into the 1990's and this blade top cutout looks nothing like his. It was made after his tenure. He may concur at a later date but it's well past his bedtime tonight.
Hope this helps, Capt. Chris
PS: The granulation and lamination on your handle's black micarta is too close and smooth for anything prior to mid-late 1990's-present...CCS
