Excellent product in both HO & O Scale. Using for 'cast iron' wagon numbers. Lots of other uses for this product. Now all I need to go with these is lettering in the same font and scales!
This is a welcome detail to apply to any of a number of Victorian masonry structures built between about 1870 and 1920. The number sets might even find use on locomotive number plates in scales larger than HO. While these were commonly cast iron, they can be painted to represent stone or terra cotta.
