No idea on the age, but I agree, he does not look like an old warrior.
I am guessing you can get a wall pedestal like the one I got for between 1500 and 2,000 depending on who you go with. I am a huge fan of wall pedestals. This is my 4th one and I'll never do another straight shoulder mount. the only down side is that they are a bit more particular with regard to where they will fit since they are looking hard right or hard left.
