I agree with the other poster who said it was a Pratt & Whitney product, likely either a R-1320 Wasp or a R-985 Wasp Junior. Hard to tell them apart from a photo except for the size

The mounting in the photo includes a not-very-streamlined airscoop for the carb intake located just aft of the oil sump, which would be at the lowest point of the engine when mounted. The T-6 Texan/SNJ had a side airscoop so it is probably not a R-1320 from one of those. Might be a R-985 off a Beech 18.

found in a basement in Jamaica. could not find a tag or mark on it.

The data plate should be attached to the front of the oil sump or the front of the propeller reduction gear case where it can be clearly seen thru the cowling opening when standing near the prop

been there some time apparently.

Apparently so. Nicely corroded.

Looks like the remains of a DC-3 engine.

This is a single-row radial. DC-3s had either Wright Cyclone R-1820 single-row radials (mostly airline use before WW2) or P&W R-1830 Twin Wasp 2-row radials (in military c-47s and later civilian conversions)

The Cyclone cylinder head/rocker covers look different and their sparkplug wire looms are in front of the pushrod tubes instead of tucked behind them as on the Wasp series.
