Memento

This is my entry for Mono Monday 'Corners'. There are a few corners on this 'gift' which was given to Guy on his retirement. I think even if I blipped the whole thing not many people would know what it is. It's the first ever fluidic pressure ratio controller to control a jet engine. The production version was on a Rolls Royce engine. Thanks to chantler63 for hosting the challenge.

I'm so sad that it appears Blipfoto has gone into liquidation. What a dreadful thing to happen to Joe and the team.
