hard to find data on the service dates, this has some break down.... http://www.ctrl-c.liu.se/misc/ram/i-16-t18.html Shows the Type 18 as the 1939 production version and the type 24 as also 1939. I'd assume that those would be the 2 most likey versions for AH.... http://www.ctrl-c.liu.se/misc/ram/i-16-t24.html Type 17 has the 2x20mm and is 1938 model.... http://www.ctrl-c.liu.se/misc/ram/i-16-t17.html A lot of variations, 20mm seem to be 150 rds each...so 300 x 20mm
