I did not see, that there is elsbeere written (blue arrow)........ I thought, that this one with red arrow is the ElsbeereThanks @Uwek ,
The rabbet was my Iwo Jima. In German you call this solution "Mut der Verzweiflung". The dealer sent me a lot of wood for testing. But the Elsbeere is very similar with my pear. There is no difference. I am looking for a much darker pear. The big block is Weissbuche.
