Nice Scout, it's a Imperial Prov. RI, from the picture it looks like a metal shield and the screwdriver/cap lifter is longer than the awl, if so it was made 1949-1955, if it has the same longer screwdriver than awl but plastic shield it is 1955-1958, if the screwdriver is shorter than the awl then 1956-1962. Scales are jigged plastic also on all three models.
