Randall has since WWII put order from service men ahead of civilian orders. Anyone can request their name or perhaps a slogan etc, be inscribed on the blade, opposite the Randall logo. Dennis Reider requested and got his name, rank and serial number. The knife would have been a private sale to the Air man. A quick read of the history of the Randall knife can be found here.

True all of this. The Heiser sheath, as stated puts it late 50s early 60s, probably the latter. The hilt, though usually double on a #1 is a special order item, and that hole for the lanyard might be as well. The nickel butt cap and handle shape I think might be special order as well. ( I think...)
Later in the Vietnam era Randall would use pretty much pre-made blades from Solingen Germany ( on special request) to speed up manufacture and delivery times, the above knife is NOT a Solingen blade but a Randall Made.
The sheath is in amazingly good shape, and is worth $$$$ in and of itself.
All Tolled, thats a COOL knife!!
