Interesting thread. Occasionally I have had one Bear TD limb sitting around with no where to go, usually after something rather unpleasant happened to it's mate. Trying to somehow match it with another similar solo limbs is probably better than two solo limbs dying a slow, sad death on their own. No guarantee how'd they shoot together, but who knows. They would certainly display just fine.
On a similar note, does anyone have a dusty, broken-limbed 1965 or 1966 Bear Kodiak laying around? I'd like the riser section for a grip-modification experiment.
Good luck on the limbs.
