That was one of Mike Roden's "I'll show you what I can make" efforts that was never seriously offered for sale.
Humorless as I tend to be about such things, I gave him heck for spending a small fortune on that "one time creation" when they couldn't keep the Bruin II units made at that time from throwing belts every 200 hours.
After
Prochem was bought out, the new management squashed Mike's "mad inventor moments". I confess, in retrospect, I miss those days.
One of the many great things about this industry is the amount of invention and innovation that still occurs here.
