If you have a few weeks to wait, I can provide some photos of my double (outside hammers, like the Kodiak) that should be completed in ~8 weeks.
It has exchange barrels in 500/465 NE; 9,3 x 74 R and12/76. It is hand engraved and I choosed color cased hardened finnish. It will have open sights on the 500/465 NE barrel set. The 9,3 will be with open sights and has mounts for a glass.
The price is somehow were you want it. I could give further info if you are interested in having one.

BTW, I had a chat with Mr. Pedersoli and the gun proofhouse on building the NE from a 45/70 barrel set. But they didn´t recommend it. (You know, it´s my money if proofing fails, so I was not willed to have it built)

I found another manufacturer and I could even choose from a bunch of options. (standard calibers are 8x57; 9,3 x 74R;45/70;444 Marlin)
