Not sure if this helps or not but, I recently got hold of a Huntsman (4-line tang; awl with eye; parcel hook; two-position flat blade sd/bottle opener implement; scissors with screw pivot and spring channel; lanyard ring on awl/openers layer, next to awl; no idea of what its vintage is) with a missing scissors spring. Got a non-keyed replacement spring (a 6-pack from DLT Trading) that I installed and, has been three weeks with no perceptible reduction in performance, or malfunction. This might be a solution for someone having a user knife or, a temporary arrangement until the correct one might be found.
