I see it is a 7 cylinder engine

I don't think so....to me, it looks like a twin row 14 cylinder
Pratt and Whitney 1830 Twin Wasp widely used on the C-47 during WW11.
Look at the number of spark plug wires at the front of the engine.

The R1830 Twin Wasp
The Pratt and Whitney R-1830 Twin Wasp engine was one of the most
efficient and reliable engines of the 1930s. It was introduced in 1932
with either a 6.1 or 6.5 compression ratio and 775 or 825 horsepower
respectively, at 2,400 rpm. To reach its designed power the R-1830
needed the highest octane gasoline available. Using improved fuel the
R-1830 reached 1,000 hp and later 1,200 hp. It has 14 cylinders in two
banks of seven. The R-1830 was used on B-24s, C-47s and the Grumman
F4F-4 Wildcat, until it was phased out by Grumman. Pratt and Whitney
built 13,464 R-1830-90C engines for the C-47 aircraft. It was also
used in a variety of British aircraft including the Royal Air Force
Catalinas, Short Sunderland Vs, Maryland bombers, and Bristol
Beauforts

Yeah, it's an 1830 I think. the cylinder head fins sure look right for one.
Looks like the magnesium geabox casing is long gone. You'll probably find
the gears lying in the bottom underneath the engine.
