I have never heard of CLW putting kits together for other companies. I also don't think they bought/acquired the Kemtron line. P&D Hobbies ended up with the RS3 kit and parts from Kemtron.
I have heard of lots of drive kits and/or parts. They were a primary source for building up a nice drive for a diesel for years along with All Nation.
the GPs I have seen are the GP35 and GP40. I think they also did the SD-40. Not sure about the GP38 but it makes sense.
I have never personally seen a GP7, GP9, SD7, or SD9 from CLW.
Their Alco PA is pretty common, there are often a couple for sale at every 2 rail show. I am pretty sure they also did an FA model, either 1 or 2.
I have seen a cast bronze version of an FM H20-44, but not an H16-44.
I have heard talk of EMD F units and E units, but again I have never seen one.
To expand they did acquire the Saginaw molds and offered the PRR H10 for years as a kit. They also did a Southern PS4 Pacific kit. At the end they were working on a UP 4-8-4 and had the frame and mech done along with many detail parts. The H10 is very common. The last PS4 kits were shipped without drivers which were back-ordered. I don't know how that worked out.
CLW was the most part a one man operation owned operated by a nice guy named Bob Smith when I knew it.
His brass detail castings always attracted a large crowd at O scale shows. he would get one or two tables and just spread castings loose all over them. The crowd would gather and browse and buy pretty much through the whole show.
Another note to confuse matters: There was another company in the 70s and 80s perhaps longer called "Locomotive Work Shop" (LWS) owned operated by another nice modeler named Jan Lorenzen. LWS put out a very broad range of kits but they were even much more in the Craftmans kit range than CLW. I agree with the other post that illustrated an FM H16-44 kit that the kit looks more like LWS than CLW.
