Identifying Walker Floor Jack

[Joelweb]

Hello-

I'm a newbie here with a passion for old tools. I recently picked up what appears to be a Walker hydraulic floor jack, and I have no idea what model it might be. Seems it is likely a 2 or 1 1/2 ton jack. It needs new seals and a refresh, and I plan to clean it up.

Any idea what model it might be? Many thanks in advance.

I think that might be a Blackhawk. @Hiball will probably show up soon

It would be helpful for ID if you took a pic from behind the jack, looking at the pump piston. Also a picture from directly on top at the hydraulic block would be helpful.

That said, look to see if it matches the model 754.

Thank you, ajchien. It sure looks like it might be a 754. Here are some additional photos. The name plate long ago went missing.

yes, the hydraulic block and pump piston also matches a Walker. The straight rear wheels were not used in many models. Its probably around 80 years old.

Can anyone supply part and instructions for a Walker 770 5 k hydraulic jack?
