Roman arrowheads or not

Quite right about Simon, Kronckew.

Thanks for the link. Had only seen him in Rob't Hardy's book.

I gather though, that some skeletal finds of bowmen, (How they know that for sure I do not know) show twisting of the spine through unequal muscle build -up.
This possibly because of starting to use the bow so young?
