here's my mini collection of ASM "dragoons"-
top is 3rd model (1991) .44 cal, note long range rear sight but no cutout in the recoil shield for a shoulder stock
middle (1969) .31 cal, 1848 with dragoon style 5 3/4" barrel & stagecoach scene on the cylinder
bottom is another 1848 (1978) .31 cal with dragoon style 4" barrel with Rangers chasing Indians scene on the cylinder.
