Here’s one I photo-ed that you don’t see too often? Built in 1940, it’s a Harlow, one of only six built!
Below, the CALL-AIR looks like a cross between two other types but I can’t decide which two? This one was a working unit for the State of Wyoming and crashed. It was sent back to the factory, and as opposed to being rebuilt as such, was “re-manufactured” using the original construction jigs. I asked the Arkansas pilot about the odd ‘pants’. He said the plane was used a lot in cattle country and the ‘different’ looking pants kept cattle dung from being thrown up through the ‘rag’ wings. The bucking bronco on the vertical stabilizer was the company emblem.
