Vintage Floor jack - help needed

[HoldenHR1966]

Please look at the following photos and help to identify what Floor Jack this is?

It has BlackHawk stickers on it but no identity tags usually that come with Blackhawk machines. SO it is possible it is a machine made by a company in league with Blackhawk such as Lincoln Walker or Hein Werner etc.

But if you can help identify the year of production and its origin maybe I can find some kit to repair the leak.

I have contacted Blackhawk and "Mr T...." has been helpful with suggestions of S-17E and S-23C Blackhawk models. However these two catalogue models don't match up to the photos.

Take a look through these:

Your little floor jack is a Blackhawk S-23.

See catalog pics here:

This is a Blackhawk S-17:

Both of these jacks use the same hydraulic unit. (see notlob's post)

Good luck with yours...

CRTDI,

Just want to thank you for your Guidance! Looked carefully and saddle size of 5" appears to make it a Blackhawk S-23 Floor Jack...

My handle twist knob is slightly different to the pictures in the 1955 Blackhawk catalogue so I would love to see a Blackhawk Catalogue from different years say 1940s and 1960s. This would help me identify what approximate years my floor jack was created.

notlob,

Greatly appreciated. Although the drawings don't match what I have I am grateful.

Thanks for the catalogue drawings that you have posted. Do you have anymore from years earlier or later??

The handle twist knob and large return springs don't match as mine has a single large return spring not dual springs.
