63, going on 64. First OU (Browning Superposed) at 22, first SXS (Model 21) at 23. Proud that my two sons, 37 and 31, have never shot anything but a SXS.

But, to your unstated point, I think the collectors and shooters of fine doubles are aging and are not being replaced. And, it's not just doubles--go to a quality collectors gun show and see if you don't agree.
