  1. One thing that's noticeable from the photos (see 1:35 and 2:08 ) is that some of them show the IS-1 with a two-bladed propeller and a less pointed spinner. An assembly which looks like it came straight off an I-16. Most likely that was the initial fit when they were rushing to try to get it flying for Stalin's parade, and making maximum use of existing components. While the rest of the photos show the three-bladed prop and a more streamlined spinner. Probably what the design team had intended all along. Also, it kind of surprised me that (unlike the later IS series of heavy tanks), sharing Stalin's initials seems to have been a complete coincidence with these planes.
