This gauge seems to be in good working condition. I blew air into it and the gauge moved. It does have a few scuff marks, but the sight glass is clear. The plastic case is in pretty good & clean shape. It does have tiny tears at both edges where it folds over. The 6th picture is of the left side. The right side is so small, it was hard to get a clear picture. The box is pretty sturdy, but in rough shape from dust and maybe water. But it doesn't seem to have gotten to the inside of the box.This was taken from a friend's father's garage. He was an HVAC business owner.
