HO scale Combine made by Laconia industries??

Hi All

At a train swap meet I picked up a Ho scale Sierra RR combine for a song. It was made by Laconia Industries, Stockton Ca

once home I took a closer look, and she is a really sharp kit, all cast metal !

Anyone ever heard of this company or when it closed shop? Or better yet,,where theirmolds went too???/ For sure I will be looking for more of these!
