Not sure if that\'s the model, a reverse image search identified it as a cp9561. I found this cleaning up at my grandfather\'s. I cleaned out the dirt on the air hose inlet and put some 10w 40 motor oil in it before trying it out. It works, however there is some slight seepage around the seals, this was tested with a low pressure air compressor, so who knows what it\'s like with a high power one. I would recommend changing the oil and putting in whatever these require. Just a heads up, I removed the air hose coupling at the tip in order to fit this in a flat rate box, can easily be screwed back in. I will include this part in a bag.
