Just for fun I took a quick tour of the guns available on some common internet gun sites. I thought this way
if my "rich Uncle" needed to know how big a check to send I could give him a total.

Also, I tried to stay with Vintage British weapons & also tried to keep makers with their their own calibers.

LIGHT (PG) RIFLE:

Westley Richards Bolt-Action 318 WR $6750
(Steve Barnett Fine Arms)

MEDIUM (All-Around) RIFLE:

John Rigby Bolt-Action 416 Rigby $35,000
(Schwandt Classic Arms)
*would have strongly considered an original .404 Jeffery if I could have found one

LARGE (Stopper) RIFLE:

Holland & Holland "Royal" Double .500 NE $49,000
(Fred Roberts)

SHOTGUN:

Purdey SLE 12 guage $29,750
(Hallowell & Co)

So, for a grand total of $120,500 I believe this is a reasonable "Dream Battery" for any safari. What I think
is amazing is that a new "H & H" Double Rifle would be a 2 year wait & cost more than all 4 of my guns.

I would also ask my uncle to throw in a 28 day safari to Tanzania to try these out!
