This 88 lb Striker air hammer came up for sale a while back for $6500 with the base and motor.
They retail for around $8000 new without a base.
I had to decline at that time, but a while later I was asked by the company again if I was interested.
The price had been reduced to $3500 because the organ builders that owned it in Quebec had welded the upper die in place.
I bought it, then I ground the die and ram true, and now it's as good as new.
I have a spare ram and extra wide combo dies coming for it.
