Vintage Lonergan vacuum gauge with original sticker on back. I think it was used, it has a black metal body which has white paint spattered lightly on one side. This is untested part of dad's estate found in attic. Some yellowing on white face. I assume from age. My dad would be retired 39 years this year. On back is original sticker caution label, pressed into metal 33 in one area and 3228 in another. Paint spatter is chipping of with my fingernail.
