If there's a difference in the saddle diameter or the lift arm width, post that up so that the OP can determine what he's got.The picture I posted is an O'Boy. I also have a 1-1/2 ton H-W, but I use the O'Boy most.
I have the H-W Oh Boy. I was ready to scrap the jack because I could could not make it lift my Ford. I was tole that the handle was too short. I think someone cut it down. I will be fixing the handle situation. I put the fancy Harley badge on the jack.Yep, Hein Werner - either WS (1.5 ton) or O'Boy (1.25 ton). I don't know when they were made, but probably anywhere from 1950 - mid '70's.
