Rare Bear super grizzly compound bow

The listing

This is a bow that doesn't exist but somehow here it is. Bear archery made a grizzly and super grizzly recurve bows, wood and laminate with nylon string. This is a aluminum compound bow with a steel string. Possibly a prototype, one off custom build?? Even the manufacturer has no record in their archives of it ever being produced. The only thing the manufacturer could find out was the tag serial number that it was produced in 1976, all other info is blank. Ideal for a collector or use as is. I have no info available after 4 months of research so no idea how to price it. Selling for best reasonable offer. Also a few other bows as well. This bow theoretically doesn't exist but yet here it is. If anyone has any information I would be interested as well.
