Hi coolford,
Thanks for jump starting the thread. Without seeing your #5 up close, and going only by the black paint on the tote and knob and what I can see, I’d say you’re right, and the plane is a Type 18 or possibly a Type 19, likely manufactured at some point between about 1946 and 1961. I think it’ll make a great user, and the price was right too!
