Since he and others were also collecting for the Smithsonian Museum, I would take today":

22lr
223 bolt
410 shotgun for small critters and birds for the museum
30-06 bolt
375H&H bolt
Thys DR in 458wm (MINE!)
Matched pair of 12ga shotguns

I could live without the 22lr, the 410 and one of the 12ga's.
