As the 460 ES and 500 ES bear kits regularly bring 2000 to 2500, and the 629ES is a rarer emergency bear kit, I would guess 2500.
I have a 629ES that appears to be NIB. I havent seen another one sell for awhile so it's hard to put a price on it. What would a fair price be if I were to sell it privately.
I'm thinking about buying a Pelican case for my 629-4 mountain gun and make my own Emergency Bear arrack kit.
Gun-check
survival blanket-check
flask of scotch-check
pair of clean drawers-check
Gun is already paid for so I can probably put together the rest for less than $200
