Garage clearout continues, please look…

Here’s another couple of items that have surfaced after many years on a dark and dusty shelf.

Item one is an Integral Pump, Type 183 MK5. It looks to be in new, unused condition. I have no idea what purpose/engines/aircraft this pump served – can anyone help, please?

Item two is a generator, Type HX2, Stores Ref. 5U/4184, 29v, anti-clockwise rotation. Can anyone advise me which aero-engines used this type, please?

As always, your comments and suggestions are welcomed! 🙂
