I have spent several hours researching a lot of 4 HO wooden passenger car kits by Gold Cost Models of Carlsbad, California. One has already been assembled and painted while the other three are still in kit form unbuilt. I have included four pictures, thinking someone on the forum might know this company and something of these kits, age etc. Any help would be very much appreciated. The wooden boxes they are in are also a work of art with the sliding lids. Thanks for any insight you might have. I guess it takes awhile for the pictures to show up for a newbie. Question does not make much sense without the pictures.
