Roo,
you are correct. it is Beckers.
As I originally noted, #1799 was built by Matt Forsyth. Since Matt prides himself on accuracy, it was fortunate I had his version as a template to build my #1798.
The project started with an older Atlas Roco boxcar. New 6' doors were installed with fillers inserted on the car sides. The unique details were all built from styrene strips with a few brass details like lift rings on the roof hatch. A PSC roof walk replaced the original. Athearn trucks with IM wheelsets underneath. There is conflicting information whether these two cars had the unique Chrysler trucks under them during milk service. If that proves to be true, Bill Davis will be making them in O scale.
It took me some time to source the decals and to jog Matt's memory of what he used. The billboard LACKAWANNA is Champs gothic alphabet lettering, the car data is a Champs reefer data set, and other lettering is Microscale Railroad Roman lettering. The most tedious part was matching the lettering of the original.
I am fortunate to have several of Ben Brown's resin kits of the DL&W 42' wood milk cars, which will be next on my build list.
For those who model the DL&W Erie and EL. Prime Mover decals is a great source!
Thank you for the complements.
Pete, the trainmasters are coming... eventually.
