Thanks for the help. These folks are in Montana. Dave Ricke lives in Wisconsin. A knife dealer gave me his phone number. I was able to speak with him last night. Sounded like he might be mid 70's to early 80's. A very nice personable gentleman. He asked me to send a picture so he could try and identify the model and or the year, or decade of production. He stated that he had made over 1K knives, but he did have records of them.
