I don't know if any of you have checked it yet but there is an excellent 18 min. or so video on the gunsmith forum showing a good deal of the building of a couple of Holland & Holland pieces (shotgun and double rifle) from raw steel to work of art. Testing lock-up with a soot lamp, registering the barrels, test firing, etc. I know it's not Winchester related, but damn if it isn't impressive and most of the people who frequent here can truly appreciate quality. The thread is named Gun making Porn. Looks like a lot of the process hasn't changed in 200 yrs.
