This photo shows the content of the kit you receive. There are two power generators in one package. Two units comfortably fit on a 40-foot flat car.
The next photo shows the basic layout of the parts.
There is quite a bit of stubborn flash on the parts, so I had to take my time to clear that off. There is also a bit of a slit in the corner of the part. It is on both generators, so I presume there is a flaw in the master and/or mold. I used a file and a knife to keep whittling away at the flash. When I was happy with the parts, I glued the radiator to the bottom piece. There is nothing to hold it in place, so I used thick superglue, and just had to hold it for a minute or two. The generator itself fits in between the small protrusions. I just placed a couple of drops of the superglue on the bottom of the generator and then pressed it into place. I used some Bondo filler to fill in the holes that I found in the castings.
The wood tie-downs and the cardboard bottom were glued to each other using white glue. I then used superglue to glue the cardboard to the bottom of the generator part. Next, I used Krylon Gray Primer to spray paint the entire part. These two photos show a close-up of the parts. There is quite a bit of detail in them.
I searched online for what color these types of generators might be painted. It seemed to vary across the board. Usually they are some bright color. I presume that the color makes them look new, and makes them noticeable at the factory installations, presumably for safety reasons. I wanted to paint mine a yellow. I was going to just hand-paint them. When I started, the paint turned out to have gone bad. By then I had put a good bit of paint on one of them. It was a Polly Scale paint, so I could wash it off with water and soap, quickly, before it fully set. In the process the cardboard piece got wet. Also, several of the wooden tie-downs broke off (they are very fragile because of the way they are cut out). In the end it turned into a horrible mess. I got rid of the cardboard and the wooden tie-downs altogether. After letting everything dry for a day or so, I used Floquil's NYC Jade Green and the airbrush to paint the parts. That went much better, and the results are better, too. Overall, I am happy with the parts. As with the other Model Tech Studios load I have built, I put the metal wire and thread in the junk bin, because they are too small to be used in S-scale. The generators make for an interesting load on one of my flat cars.
Here is a photo of the generators on a PRR FM flat car. I still need to add the rigging that holds them in place. The loads are not glued to the car. I don't know if I want to do that.
