Produced by Replica Railways, the numbers used are from a sheet to be used for TOPs Class 47, 50 & 56 in their 2mm scale range.
The numbers needed were just rubbed onto black plasticard with a soft pencil. Then the plate was cut to size and superglued in place.
The lower picture shows how bad my alignment of the numberplat kit is.
However, it's done now and from a distance seems not too bad.
