Rolls Royce Merlin Engine Supercharger casing with impellor

Here we have a very nice Super charger casing from a Rolls Royce Merlin Engine.

Un damaged with no cracks . As can bee seen from the photos the impellor is still fitted, however it does not move. I have not tried to release it as I do not work on engines and do not want to take the risk of damaging it through ignorance

Plenty of D part numbers as shown. Any inspection welcome.

It would certainly be good for a static and probably suitable for a ground runner pending the relevant checks by a suitably qualified person.

This may reveal that due to its condition it has a potential greater than ground running.

Obviously due to its weight collection would be preferred unless the buyer wishes to arrange their own packing/courier
