What is this?

[Luggsey]

I thought it was a high quality bike pump when I grabbed this at the recycle for a £1!
It looks like a pump, when you pull it and pump it the pressure is held?
What have I bought!
It's beautifuly made with stainless steel and brass fittings?

Might be an aircraft strut pump....

Air rifle pump according to image search.
Yours looks a nice quality one.

Handle grip missing on one side though?

It's a 3 stage pump for PCP air rifles. Capable of some decent pressures

Yeah I had a bottle when I had my hw100, sod pumping it by hand

 

[Luggsey]

I was almost right then!
This one's missing the pressure guage and maybe a safety valve at the back?

There should be a gauge on it, although not a necessity as the rifles it is designed to fill will have a gauge.

There should also be a bleed valve to drop the pressure from the whip hose before disconnecting from the rifle

Could be missing a dessicant water trap.

Some will require the gauge. On my S16 you have to remove the bottle to fill it.
Does have the advantage of lasting ages plus you can take multiple bottles out with you..
