Boxcar, funny you mention that. On Monday Im going to a place that sells colored acrylic and just cut to fit squares and clip them in as a temp fix. Will still look decent until letters can be made or found. As for getting them made. The money is in getting a mold done. They can be reproduced but its not cheap.
Mainly focused on Oilzum, Jenney, Harris Oil items & original paint gas pumps.
