From the late 1920s, three locomotives - 3655, 3612 and 3610 - were adorned with cast brass cabside number-plates, a departure from the usual individual numbers.  3612's lasted until the 1950s.These are HO Scale reproductions of these plates.  At that time they were installed, all locomotives had their original cabs and round-top boilers.
A set of two of each number (six plates in total) is in the pack.  Etched brass.
