Timothy wroteSaw this on EBay and looking at the key blank. This first time seeing this round Yale blank. Just wonder if anyone know key blank number and I know this going to be really hard to find the key blank…Timothy…
That’s the Old Yale 3-½ blank. Here are the known substitutions from Blackhawk KBX: 31 Dominion, A50 Atlas, 639 Dominion, S26 Niessen, 126 Niessen, 251 Keil, 230 Curtis, S251 Keil, S26A Niessen, 1031 Ilco, 1239 Ilco, 2667 Stewart, T113 Taylor, 1239S Old Ilco, 2790A Graham, N2790A Graham, 2790AM Graham.
Note that of all of those, only 1031 and 1239 Ilco are extant; but they do not have the round bow.
