Indeed, it’s a Rolls-Royce Merlin and not a Packard Merlin if it still has its original engine. My reply to Jame’s comment was poorly worded.

Have been watching the series on ukTV dedicated to the re-build of MJ755.

I believe it does still have its original engine, yes.

You are correct in your understanding of the RR vs Packard Merlin aspect. The Mk IX and Mk XVI differed in their engines, but also had a few other minor differences. While most airframe parts are interchangeable between the two marks, parts associated with the engines generally aren’t. As you state, the availability of Packard Merlin engines and parts is not really an issue. There are hundreds of Mustangs and other types flying with them today, and a market to support their operation.

Interesting about the aircrafts originality. I assume it still has its Pacjard built 266 engine? The Packard USA built engine was fitted to the MkXVI’s, hence they were designated MkXVI’s, instead of MkIX’s. The reason for this different Mk number was I understand, due to the parts of the US built motor, are not interchangeable with the RR built Merlin, (different bolt/nut sizes and threads for example). Is it not a problem to overhaul a Packard built engine? I suppose so, if its only the hardware that is different? However, if drillings and tappings on a cylinder block or head are differeewnt, it does mean you can’t use a Merlin part? I guess a lot of Packard parts are available in the US?
