The Zeiss-Ikon Super Nettel (and a kinda-cool “camera people” story)

The story of how I acquired and then re-acquired an awesome 1934ish Zeiss-Ikon Super Nettel, with special thanks to the super cool dude in Japan who fixed it for me. Note: I was wrong about the Contax I having a combined rangefinder/viewfinder window. Note 2: I found a couple of the archival camera photos at random sites online, apologies for not crediting the sources. If I got anything wrong about the history or operation of this camera, please let me know in the comments.
