VIBRO ROLL B-17 Olive Drab HP

Here's an interesting little toy from the 1940s, the venerated B-17 Flying Fortress. The toy itself is rather a mystery and I couldn't find anything more specific than one photo in Bill Hanlon's book "PLASTIC TOYS Dimestore Dreams of the '40s & '50s' " which attributes a plane that looks just like this as being made by VIBRO ROLL Products, USA. The dimension for that plane are slightly different than this but the similarity is there. It measures 4 3/4" (12.06cm) L x 5 1/4" (13.33cm) wingspan x 1 1/2" (3.81cm) H and has no maker's mark on the plane.
