1. I have attentively looked. Probably it is simple serpentine
2. The interpretation of hole in wood. I think that hole help to hold slowmatch during time of reloadind or firing.
3. Still which that that helps to date is an hole in wood. I did not see such after 1500. Hole in wood usually is drawn on images obout 1470-80.
