Found at a swap meet, it has a reed valve, steel cylinder held down by two screw clamps, provision for a spark timer and no markings except for the number 825 stamped on the front.
It looks to be around a .15 or .19 size.
What is it?

I have a model engine plan book (The Motor Boys International Model Engine Plan Book), which is a collection of plans for home built engines. What you have looks an awful lot like their article on the Scrapper 29, which was originally produced by the Woodbridge Manufacturing company in late 1944-1945.
But there's a bunch of details that are slightly different on your engine, and it looks too good to have knocked around someone's shop for 65 years -- I'm thinking you have a reproduction (possibly a good one). Everything would have been hand made, so it's conceivable that yours looks different from the picture I have because of that, and that it did sit in a climate-controlled room for six decades -- but I'll vote for a repop. If it's really a 19 and not a 29, it has to be a repop -- my article says that the bore & stroke are 23/32 x 3/4 (don't blame me for the units -- that's what's in the plans that I have).
So, other than some construction details, you now know what I know.
Here's a page on it's big brother: http://www.modelenginenews.org/prod/supa_scrap.html. If you feel really motivated, inquire with the editor of that web site -- here's the front page: http://www.modelenginenews.org/index.html.
