View attachment 810986 From what we can tell this may be made by National Standard. This is not hydraulic It is mechanical. Any further information would be great! It says the same on both sides as last pic. It's just harder to read on the other side. also did National Standard ever make jacks for Walker. It looks likes Walker. Face plate is stamped S1420 not shown. Thanks - Sheryl P.S. larry_g I could not send the picture you requested and had to start a whole new thread. Thanks. I hope you get this
