Hi apparently dad bought a couple of war surplus engines and stuck em in the barn they have these markings on a plate "packard built rolls-royce aaf model v1650-9" appears to be some kind of aircraft engines don't know much about them they appear to be in good condition. Would they have any value? they are huge defiantly worth something for scrap.
Yep, that's a Packard-built Merlin tag. Hang on to them and get a qualified aircraft technician to take a look at them. Depending on condition, these could be quite valuable. DON'T scrap them!
