I consider it a privilege.

I get to do a promo for my pal Ryan Mendell and his new company, National Scale Car.
Ryan, who has done much of the pattern work for Yarmouth Model Works of late, has branched out and created his own model business creating bits and pieces for those of us who like to build accurate freight car models.
I just finished 2 cars for myself using his new "10′ Height 7 panel Superior Doors with Union Duplex Fixtures" parts.

The door set also includes a very nicely rendered etched door track which is fairly simple to install.

Simply shave the lower track off of a IMWX/Red Caboose boxcar kit, create standoffs from styrene and secure to the back of the etching aligned with the etched holes.

Trim the standoffs flush to the track edges and secure to the car side.
Drill through the holes with a #79 and add short bits of wire and clip them flush and you'll have a very secure attachment that suggests rivet heads.

From there you can detail the car to your hearts delight.
In this case I was modeling SP B-50-20 boxcars.
I tossed the factory brake gear and used Tichy parts, and did a full underbody detail, rods, air lines, etc.
The ladders were replaced with YMW ladders and rungs.
An Apex running board from YMW was used as well as the brake step.
Kadee bracket grabs were added
I managed to find some Detail Associates Equipco hand brakes.
The paint is Scalecoat Boxcar Red 2.
Decals from Speedwitch Media.

My fleet of SP '37 AAR design boxcars grows.
