Haenel Sport Model-33
Haenel Sport Model-33 Junior.
This was a 1930s youth-sized 4.45mm lead ball repeater and reputedly a favourite of the Hitler Youth. Not to be confused with the adult-sized Sport Model 33.
It came with a six-ball magazine. They were also available in 8 and 12 shot and the post-WW2 Haenel (eg. 49a, 49, 310) and Anschutz (275) magazines are not the same but can be made to fit in the pre-War rifles.
