New dendrochronology evidence possibly pointing to a connection between Strad and Amati. The rest is mostly a summary of what we have discussed - almost ad nauseum - re Strad's secret varnish or method of wood prep. This article implies it might just be animal glue... Anyway, I think an interesting summary, with of course, the typical slight inaccuracies expected from non-players/non-makers. This article does give a few details as to where and how samples were taken and examined. Plus lots of good references.
What do you think???
