Dating Bohm Waldzithers

This superb research work has been done by Norbert Feinendegen in Germany, using photographs of the old labels, and old telephone books from Hamburg, and Martina Rosenberger's research in her indispensable book "Das Waldzither-Puzzle", Part 2... it should enable most Bohms, except the later ones, to be dated to within 3/4 of years, though these are only 'guestimations'. I would like to thank him for letting me use his research here, and recommend Martina's book to anyone interested in waldzithers, though it is in German.
