On the early A.H. Fox Gun Co. guns, especially that first block of serial numbers 1 to 3000 that we speculate were made at Wayne & Bristol Streets, we normally see the line on the bottom of the tubes ahead of the barrel flats -FLUID-STEEL-KRUPP-ESSEN- but on some guns we see a second line -HEAVY-WEIGHT-BARREL-. At the winter Las Vegas show I examined a gun, serial number 7144, an early gun from North 18th Street and Windrim Avenue, that had the line -LIGHT-WEIGHT-BARREL-.
