Hey, those pictures of my airplane aren't the best angles for an ID so I'll give you a hint or two----it was manufactured in the 1930s with a 90 HP 5 cylinder Kinner radial but this one was converted to a 120 HP 4 cylinder Phillips engine (Manufactured by Glenn L Martin Motors Co) by Dick Probert.
Dick died last month at age 101--he hadn't flown the airplane in 16 years. We pulled it out of the barn last Monday, drained and refueled it and it started on the first blade when I propped it........
I know you'll be able to Google something out of all that info
And, Thanks for posting those pictures G-man
