Old some sort of manual jack

[threeputt]

Its been in my shop for probably 55 years laying back in a corner. Just wondering if this was used on dozier tracks to adjust them ? I know its heavy. Has numbers on it but google don't come up with anything. Anyone know what its was used for way back when ?

Yep. I worked for BAE outside of York. We made M88 retrievers, M109 howitzers and Bradleys. All had one of those and spare track links. The bar was a "tanker bar". One of those on all vehicles also.
