I have been looking through my old Scottish Air News and Scotland Scanned issues as both have info on the contents of the Arbroath dump over the years. I’ve only come across one Sea Hawk coded E on the fin and that was WM939. However, that’s not the aircraft marked Radioactive and coded 82? which is a different aircraft altogether. It took me quite some time to spot it but the starboard wing is missing from that one and therefore no underside wing serial would be visible in your other photo. They are two separate aircraft.

Haven’t managed to find a Sea Hawk at Arbroath with a code starting 82 yet!
