Evening HP,
Couldn't resist your goodnight clue!! It was the follow on project to Paul Maiwurm's 1929 "Fly Wurm", don't know if it had an official name, possible called the Cyclonic Rocket, it was designed in 1934, but remained un-built!
In the workshop all day, just getting something to eat before hitting the hay before another 5am start, so Open House please if you're happy to pass that for an answer
, Cheers TC
