quite a new engine then, that'll be why I don't offhand recognise it since Avon's and Spey's were the in thing once up Boscombe

Quite a few operators of Twin Squirrel's, looks like this bloke needs to track down a contact who has access with first line maintenance information, unfortunately I don't as Boscombe lease-hires the Twin Squirrel for the Empire Test Pilots School and all we do is kick the tyres and light the fires with it
