Speaking of “priming”, it was always fun to start up the R-1820 at night time…
Despite its size it was a very agile helicopter.
Fun to fly.

Regarding the magnesium skinning, for technical reasons we had to leave a S-55/H-19 (similiar in construction to the H-34) on Bird Island /Port Elizabeth South Africa for a short while(early 1970’s). Upon returning we could push our fingers through the a/c skin!
That was it for repairs!

Have Fun and Good Luck with your work.
