Malcolm
That is a beautiful job of fabrication, painting and lettering. The Glacier Green looks very good and the over spray on the roof is nicely done. It is also a wonderfully creative use of an old kit. Every old kit that gets used to make an otherwise unobtainable model is one less old kit headed for oblivion. Your GN waffle side car is just the sort of model that will be adding character to a train of other ready to run cars for decades to come.
For those who might not know, Malcolm's use of the underframe, roof and ends from an older car kit is totally appropriate for this model. The real GN 4200-4399 waffle side box cars were rebuilt from 1940s vintage plywood sided box cars. The GN reused the underframes, roof and ends and fabricated new sides to take DF2 bars, hence the waffle sides. The 10 foot doors allowed easy for lift loading. These cars saw extensive use hauling wood and paper products. Some were in assigned service to specific shippers.
The GN 4400 series box cars would also be perfect candidates for modeling in this fashion. They too were rebuilt from plywood side box cars. Their ribbed sides lacked the "waffles" since they lacked DF2 equipment. They did have one extra feature, a grain loading hatch in to top of the 10 foot plug door.
The 4200 series cars were about the last to get Glacier Green paint. The 4400s may have been the first to get Big Sky Blue with the new simplified Rocky herald. Both series are interesting cars and we now have a great example of how to model them.
I do have to say one thing. And this is in no way a criticism of Malcolm or this super cool model. I just can't understand why All Nation put PS-1 style ends with Murphy Roofs in all those kits. Using 4/5 Dreadnaught ends for the GN 4200 and 4400 series box cars would be prototypically correct. I'll have to stay on the lookout for an Athearn kit.
