Question: What weapon, designed by Aimo Lahti, was a descendant of the M-22 prototype and the KP/-26 production model?
Sentence (from "Sport (camera)"): The actual launch date of the "Sport" is somewhat uncertain, however it must undoubtedly be one of the two earliest generally available SLR cameras using the 35mm film format, the other being the German Ihagee Kine Exakta, launched in 1936.
Relevant evidence: No
