During the holidays I have done some renumbering of duplicate PRR freight cars. Some time ago I had bought (almost) all Microscale sets for the Pennsylvania, but all box car sets are for the "shadow keystone" era, which has a different number font than the "circle keystone" era. The cars were all circle keystone so far.... The only set that had the correct font were some pieces of Fine N Scale decals that came with their resin models. They don't last very long. Are there any other source for PRR decals, or did I overlook something? The decal set for the F30 flat cars might have the right font, but I am keeping these for my Alan Curtis car kits, and maybe further kits from Peter Harris. Thank you for hints and advice.
You might want to take a look at the Microscale PRR caboose set and the Microscale Merchandise Service set. From what I can tell online, both appear to have both styles of lettering and possibly numbers.
