The Z&H have two hand pnumatic palm buttons. The Osterwalder can be switched from two palm buttons to foot pedal and has hydrwulic controls . They were used for cold striking brass insignia. They were oiled twice per day when they were run. You can see the oil on the gibbs and running down the arms!

I have some old Z&H literature. It goes like this. Z&H rate the press as the square of the number. 5=25 ton, #7=50 ton, #8 1/2=75ton, #10=100 ton, #12=150 ton. The tonnage is somewhat(a small fraction) adjustable by stacking hardened plates under the die. The percussion press hits hardest on the last fraction of the drive wheel. Here are some pictures of the machines I have left. I love them like my dogs!My dogs take up less room! John Asking price is as follows: Z&H #5-$900, #7-$1,900, #12- $3,500 , Osterwalder 125-$4,000

I have a Z&h no.5, a no.7 and a no.12 for sale. I also have a nice Osterwalder for sale. It is between a z&h 10 and 12 in power. I am not a dealer. I just don't need them anymore. Nice machines. At one point, I also had a no.10 and no.8 1/2. I'll post pictures later today. John
