This one is RAILROAD all of the way. A Hamilton 16 size, 21 jewel, lever set, open face, 992 that should still be on the railroad. It has a double sunk dial with bold black Arabic numbers, red five minute markers, and signed in script “Hamilton”. There are a couple of hairlines and a chip I think.This good looking ¾ Nickel movement is signed in gold lettering “Adjusted 5 Positions, Double Roller, 21 Jewels, Made in U.S.A., Hamilton Watch Co. Lancaster, Pa., 992”. It comes mounted in a 10K gold-filled Hamilton Railroad Model SB&B case with the Pennsylvania Railroad emblem on the back. REALLY COOL!!!! A RAILROADER’S DELIGHT!!!
