Looks to be in really nice condition! Can you give any details on ammunition - whether you facbricate it, reload it or buy it? It is an odd caliber, but I've seen a higher percentage of these in shootable condition than any other rifle from that era.
I have crafted my own cartridge cases for non available calibers, and I am curious about this one in particular.
I have to confess that I didn't watch the video - my sound system on my computer is in the fritz.
