Grandpa Jack, from experience, I would recommend you contact them by phone, and set up to phone bid. It allows you to bid live at the auction, and gives you a much better chance at getting what you are going after. Auction estimates are generally close, but if a couple people want an item you could lose it with an absentee bid. These auctions go pretty fast, and what they will do is call you two or three items before yours is up. I generally tell the phone bidder a number they can bid to before they need to ask me for a bid or no bid. The last gun I purchased, I gave the bidder a $3,00 limit to free bid. When it reached that number I gave the ok to go over, and I won on the next bid. PS they're a very reputable company.
