Thanks for this, very interesting. I didn't know this rifle was ever offered in .404 or 10.75x68. It must be very rare in those calibers. The rarest caliber in the Browning Safari I think is .284 Winchester. The .222 Rem Mag is also rare if I remember correctly. These are very nice rifles. I have told the story of midnight shooting of Browning Safaris in .375 and .458 with an eccentric gentleman I knew in my 20's, so won't repeat it, but very fond memories.
