How fortuitous! Ever since photographing this and two other like boxcars at FWWR’s headquarters a couple of months ago I’ve been looking for one with no luck. This one even has the correct number of external ribs on each side. Perfect! I’ll be buying more than one. While it’s true the ends aren’t quite the same they’re easy enough to swap out.
I’m really digging the ones on the model - five ribs between each of the riveted sections, just like in my photo. And as the ends seems to be inset somewhat, I don’t even think I need to remove them to replace them. Not fully anyway. It looks as if I can cut out the ribbed portion and leave just a little plastic at the top and sides and attach another and right over the remaining lips.
I’ve just noticed that I do indeed need one of these, but that the other three boxcars at FWWR are different.
This one, while similar in design doesn’t even have double doors, but the one door is similar in design to the Youngstown door you mention. It would be easy to do, but I don’t even know if I want to use this on a layout as it sits in a location on the far side of on offramp from I-35, which I have no intention of showing.
