Hi kiababbuck. From the year 1950 to 1952 Model 1000 and 1100 Husqvarna Vapenfabriks AB were available. (mine are model 1100) From research I have done by the serial numbers I am guessing that they are 1951. The years 1950 to 1952 are the vintage I am looking for.
Model 1000 and 1100 were made between 1950 and 1952 in 270 Win, 220 Swift and 30-06. Model 1000 was a "Monte-Carlo" version and Model 1100 a "De Luxe" ditto. Both were drilled and tapped for scope and/or diopter mounts.
