Wanted a postwar PRR observation car, since they actually had more of them than the more traditional looking prewar observation cars. Except there wasn't exactly an affordable way to get one. I believe Golden Gate Depot made one included in one of their sets, but it's not like they show up for sale very often, and when they do, they're not exactly cheap (especially since they're usually sold as part of a set).
Figured I'd use the K-line open end "business car" as a starting point. I'm sure it had a prototype, but it sure wasn't from the PRR. Working from photos and car plans (and, of course, squeezing an 85 foot car into a 72 foot space), I designed a replacement end, printed it, and decorated it. If anyone's interested, I'll explain the steps I took along the way, but here she is, just about finished...
The interior lights have been replaced with LEDs, the drumhead is lighted, and the rear marker lights illuminate (3 mm LEDs). There's also a removable bar that bridges the gap below the coupler, but it's not in place in this photo.
