Thanks a lot guys for the ideas!
Fleshpeddler....now you show up!!! After I purchased those 2mm letter punches!!! 2mm is exactly what I'm looking for and the ones you have for example are what casted digits should look like! The ones stamped on the tamiya look too perfect and thin.
Do you have any sites in general that would have it? I've just looked at modeltrainstuff and a couple others and none show.
