Hydraulic Hand Pump. What is it off?

[Grant Bowker]

It is not the pump used in the 60 ton press that was mounted in the 60 Ton Press Trailer covered.
The manual for the press trailer references contract C.D. LV-587 on the cover. I have the impression that the same contract was used for many types of machinery lorries, can anyone confirm of deny this for me?

Thanks for all your suggestions Please keep trying

I have found a very small number stamped on the top cover - 2670. Not sure if it helps but this seems to be the only identification marking.
