Anyone seen these - 6-Stage Cylinders

[tman1986]

Hey i was wondering if anyone here could shed some light on what i have found

it's about 12cm long closed and over 50cm open, i origonally thought it was a 4 stage cylinder but when i received it there was 2 extra, i bought it off ebay it was a random miss spelled auction so i thought i would take a shot

it's made of stainless steel, it has weight, my question is who makes this?, what was it's cost new?

there's no markings on it anywhere, it looks similar to scalearts put there's too many differences (the top hole instead of a ballstud, square base instead of round, almost same length,maybe a little longer but 2 extra stages)

and it's defiinitely designed for hydraulic use

if anyone knows anything please fill me in i'd really appreciate it

Thanks
Trevor
