I recently acquired this piece for use as a forklift Jack. I told the fella that I bought from that even if it didn't work it would make a substantial doorstop. I am curious if anyone knows the brand and/or age of this unit. The unit weighs 127 pounds and I find it quite interesting in that it appears to be extremely well-made in that the track that the actual tow hook slides up and down in appears to be bronze. I'm attaching four different views of this unit. Thanks for your help. Dennis Dvorak [email protected] I am naming it R2D2
