A few years ago I did some fieldwork at Djurhamn, a peripheral naval harbour of the 15th through the 17th centuries (and blogged much about it: A - B - C - D - E - F - G - H, and published a paper on it in an anthology). Now maritime archaeologist Jonas Wiklund has published a paper on the sad fate of the Rikswasa, a nearby shipwreck that was salvaged by a diving firm and made into coffee-table ornaments in the 1960s with permission from the National Maritime Museum. Jonas has kindly allowed me to make his paper (in Swedish) available here on Aard.

I have one piece from Rikswasa - given to me as present on some birthday, because I like old things. The piece is a thin, little plank. Obvioulsy taken from a bigger piece. Sad.
