Board mounted and not tin based ..... yeah, I'd say that was a super bargain to be sure!
I managed to score a tin base #30 a few months back that was essentially like new, nearly unfired, but with a slight dent in the top of the boiler. The dent came out pretty easily and almost completely, to where you have to really look for it and know it was there to begin with. Felt like I scored pretty good on that one at $67, but with S&H plus tax it came to a bit over $90. Still, one heck of a deal on a fairly rare engine.
Your wood base is even rarer I'd say!
