These make me wonder if Ruger had a hand in this production. There area a couple models there that would not seem to be there were it not for a hand from Ruger.
The engraving looks more like Baron's "selective gold layering" than true gold inlay, and if they were done by Baron, would give even more credence to the Ruger factory having something to do with the end products, although the box labels do not indicate this.
I see there are a few calibers missing also that have been made through Ruger's #1 History (.338 Win, .416 Rem, .416 Rigby, 9.3x74R, .404 Jeffrey, .22 Hornet, .218 Bee, .264 Win, .30-30, .450/400 NE, .450 NE, .257 Roberts, .458 Win. etc. etc. don't forget the PPC's).
