Must be after 1980 because of the numbers, they got the Champion that was retired 1985-86 and there is the combination tool that came in 1982 on 84mm.My guess 1983
My guess is it between 1980 to 1985. because:* it is 1980+ soldier* no the plus scales (pen / pin) (1985) * no hole in the reamer (1985).* "victorinox" on the blade - small 'v'. (I am not sure if it was untill 1984 or 1985)I even think it is from 1982-1983 because:* no mini-screwdriver (1983)*double spring in the scissors - as far as I know it started on 1982/3 (I maybe wrong with that one).Thanks for sharing the catalog. I love old catalogs
These soldier knives were made between 1977 and 1987.The V-shaped scissor spring was introduced in 1975.The fine screwdriver is already on some models, it came in 1977.And the Gran Prix still has the square philips, the round one was introduced in 1980.The Combi-Tool has a different shape than today (introduced in 1986) , maybe an early variation.So I think the catalog was made between 1977 and 1980, maybe closer to 1980.
