New vintage Manley jack

[Railguy]

I bought a vintage Manley jack i need help identifying. I can't find any information anywhere. Any help would be appreciated.
Sorry about the one pic. The sun was bright and I could hardly see. I wanted to use the pic with it on the tell gate for scale.
Thanks railguy

There doesn't seem to be much info available on Manley jacks. Google search mainly links you to other GJ threads looking for similar info:
