Less than 200 from what I've read.That does make for a rare bird.
you may be on point. i wanted to say 250, but imagined that figure was too low. i am inclined to agree with your figure as it was years ago, on the Steinberger Forum, that i searched for info.
in your estimation, what is the average value of the white ones?
thanks to you & number11
