Apparently this CZ82 is not worth as much as I expected. With 16 hours remaining in the auction, the winning bid stands at $355. I had anticipated a range of $400 plus or minus 10%. My actual delivered cost for this totaled $360, so it will be a real disappointment if it goes no higher - but, Oh well!
This is only the second time I have tried to sell a firearm on GunBroker. Perhaps there will be a flurry of activity (would like to see a frenzy, but at this point that looks like wishful thinking) overnight.
