I’m a first time poster to this great site. I have a #4 Proving Machine Serial #9009 sitting around getting rusty. Does this press have any value, and what would be the best way of selling it. We’ve had it for at least 35 years, and during that time, it was used rarely for ink testing in our lab. Any info your can offer will be greating appreciated! I can supply pictures if anyone is interested. We are located in central New Jersey.
