A recent bundle of magazines included a number of 1946 and 1947 issues of American Helicopter magazine. The December 1946 issues had a "Helicopter Panorama of 1946" spread and the following designs were presented. I've included a couple that were actually from Canada for completeness.
As my dear Mark found this drawing to a Haig helicopter Project,also the same designer created a helicopter,
actually built and called HK-1.
Any indication of scale?I posted a picture of a Grumman proposal that was in the collection a while back. Well joy of joys, I just added a minty in the box Grumman Design 376 AAFSS with the original stand that will help with the lineage. Seems Kaman was involved as well. Enjoy!
Not Ursham but Urshan after its builder Sam Urshan of San Diego, CA (who was a PR guy for Rohr Aircraft Corporation).Mr. Samuel A. Ursham designed a little helicopter,called UR-1 Air-Chair in 1957.
