First of all, if this has been posted here before, apologies.
I don't know anything about it except what's shown. It looks like it would have been
fiberglass, <strike>and the time frame is right (1972)</strike>, but considering it was 1936 I'm not so sure.
Whether it was just a concept drawing (my guess) or actually existed, I don't know. If only we
could see page 41!
Pretty cool though!
Edited to fix date mistake.
