This is an extremely nice old brass steam gauge made by Ashcroft for AS Cameron Steam Pump Works. It measures almost 12 inches in diameter and the face is about 10 inches. It's a bit different than most gauges that I've had or seen as the bezel retainer unscrews rather than slips off of the front. It has been displayed on the oak board and has some kind of lacquer or hair spray on it to preserve the patina but I'm sure this would remove easily with some... thinner if you so choose. There are no cracks, breaks or repairs that I can see or know of and it has a great look to it. It would be a fine addition to your steam gauge collection or display. These large steam gauges are quite tough to find so if you've been looking for one don't miss your chance on this one. It's ready for display! Let the pictures be your guide. I can be reached by phone or text message at 262 573 1931 if you'd like to talk about it. Good Luck.
