When is ‚oldwood‘ considerd to be ‚old wood‘? How old are they really? How relevant is the actual age or does it depend on how wasted the surface is?
Thats excactely right! Sunburnt Boards, for example are sometimes really old (50-150 years), sometimes it only takes 20-40 years until they are weathered/sunburnt enough.
Handhewn wood – on the other hand side – can’t be any younger than approx. 100 years, since it‘s typical surface was done by hand & axe, when machines where not available.
