Doman helicopter projects

[hesham]

Is anybody familiar with the designs of Gliddon S Doman? This larger one was shown in "Der Flieger" magazine issue 9/1954 (page 206), but nothing about a D-... designation ...

As I expected before,it was not an ASW helicopter project,but it developed from it as a 20-passenger
commercial transport helicopter project,powered by three General Electric T58 engines.

Aeroplane 1957.

I recently came across this very lousy picture of a 1958 helicopter refered to only as the Doman D-12.

Has anyone heard of this one before? It could be a small R/C model of course, but it could also be a genuine prototype. Hard to tell given the poor quality here...
