I’m hoping that someone might be able to help me out with an ID on this thing I found on a remote moor in northern England. It looks to me to be possibly an oil cooler from an aircraft, but no idea what type. There is a lot of other debris scattered around, but this was the only thing with any marks on it. I will take it back to where I found it over the weekend and photograph some of the other stuff, but in the meantime any help would be appreciated.

Its 24cm x 28cm x 11cm in size. There is no record of a WWII crash at this location, at least anything that I can find. The landowner doesn’t want a big fuss but is happy for me to try to get an ID and if it is unrecorded, will give permission for a proper licence to be requested and an investigation.
