Info needed on old Grizzly

[Cuerno Verde]

I got this old Derco Grizzly cat stove and was hoping I could get any info on the model type and rough age. No UL plate to be found. Any links to manuals or parts diagram would be great. Anybody own one?

This may help a little.

This stove has a 7 inch X 2 "puck" type catalyst. Does this simply sit in the ring that is bolted to the burn chamber lid, or is a gasket or furnace cement needed between the cat and where its seated in the ring?

I also bought a home with a Grizzly. It has the same puck style cat. I need to find out how to remove it. Do you have a manual, or know how? The holder is no longer snug against the roof of the unit, and I would like to repair it.
