More Flat-Car conversions

Last year I bought a lot of 2 used flat-cars. I actually bought it the just to get one of the flat-cars, the upper one in the following photo looking like a heavy duty one. The lower one just came with the deal and I have several similar of this type in my collection already:

Heavy Duty Flat-Car

In my fleet of Flat-Cars I wanted some of them to stand out, and this one looked like a larger 'heavy duty' Flat-Car for heavier loads. It also looked almost ready as is and would need minimal efforts and changes to be ready for military service in a rake in some of my G-scale military trains:

This is actually an American Standard Gauge Flat-Car by Accucraft, which also runs on 45mm gauge. I wanted to make it look more like a narrow gauge car so I 3D printed and added buffers to the buffer beams. To the buffers I added hooks for the 3 link couplings for my WDLR train:

The bogies were of an American type and had American knuckle-couplers attached to them. As I don't use this type of couplings on my rolling stock I just tried to replace them with LGB ones, but they didn't fit very well on these bogies. So I replaced the American bogies with LGB ones which had original LGB couplings attached. The LGB bogie (lightly weathered) to the left, and the original American one I replaced to the right:

The floor was given a blackwash followed by a drybrush, and I washed the wagon sides to make the rivets looks rusty:

The other Flat-Car in the job lot

I have several similar Flat-Cars of this type already, but it followed the purchase. This was brown and had American lettering:

It didn't have any buffers usually found on narrow gauge rolling stock, so I 3D-printed some from a free stl-file found on Thingeverse:

To make it fit my other military rolling stock I just spray-painted it grey in a slightly other shade than the similar Flat-Cars and painted the floor:

Salvaged from spare box

This is strictly not a pure 'Flat-Car' as it has more similarities to stake-wagons. It was included in a job lot I bought a couple of years ago. I couldn't use it as it was so heavily used that it's axle-slots had become oval and the wheels didn't spin properly and the wagon wouldn't roll anymore. I didn't buy the job lot for this wagon in the first place, so it was sent to my spare box for future projects. 

While working on some of my other military 'wagon projects' I got some Miliput left over and I decided to stuff it into the oval axle-slots to see if I could repair them. When it was completely cured and hard I drilled new holes for the axles. This seemed to work, as the wagon and wheels were running freely again now. Then it was given a coat of grey paint, had the floor painted and finally given a blackwash and drybrushed:

I didn't make any loads which I fixed to these cars as I want to be able to swap out different loads on them.
