I just purchase 3 Kern Valley RR. heavyweight passenger cars and would like to know some history of Kern Valley RR. Did they build the models? Was Custom Model Products involved? The seller said that these were the only ones built by Kern Valley RR. I looked this RR up on the web and it seems that this was a full scale railway, so if anyone knows or has any information on these 1:32 heavyweights, please let me know, thanks. I will try to upload some pictures, Bob.
