Here is a good bar. I do not know the application and see no markings on the bar. I cleaned off the rust, painted it silver and checked the rails square. It is a torrington nose and free but tight. The slot is about 9.5 mm or about .370 inches. You can see the holes for the mounting. It is about a 38 inch called length and 40 inches over the entire length. It may make a good milling bar for you. Appears to be straight and .063 gage. I would like to see $100 for this but remember your shipping may be expensive as this is heavy, bulky and you may live far from Dayton Nevada.
