Good find Chris. Looks like Mr. Maurice Poirier has a nack for sci-fi and is way ahead of his time for 1937. I would like to have seen that test launch from behind a concrete bunker !
A couple of other thinks I noticed in the photo is the size of the rafter tails coming down from the roof system. They are true 2 inch by 4 inch 2x4's and they also look to be cut by hand with an handsaw. That was before power tools came along .

PS. Please don't call me Mr.-- Makes me feel old and I'm only 39 and holding .
