Bear, Browning & corkscrew BH help

[highcountry]

A guy in town asked to put a $$ on these toys, you guys have any input.  I really do not know too much on these:
 
Bear Grizzy. Serial # KR73525 AMO 58"  40#. Grayling MI. Coin looks silver. Has a stabilizer bushing.  I guess fair condition, some scratches, not too bad.

Browning Nomad Stalker, serial # 4W2655-1  50# @ 52", two stabilizer bushings both upper & lower limbs, like for target FITA and a regular bushing in the riser location.  Has the paperwork, 1974.

Now for what I think is the "cool" items.  He has these cork screw twist Browning broadheads, he only wants to sell four of them.

There were several models of the Browning Serpentine that were produced. Some are very common, some are scarce and some are extremely rare and valuable. Would have to see a photograph to determine which model you have.

There are 8 different models of the Browning Serpentine shown on pages B-54 & 55 in "Broadheads 1871-1971 Identification and Rarity Guide, Second Edition". Half of the 8 are shown with a Rarity of from 1 to 8 known in collections. The other models are far more common.
