If what Rae Faltysek has is a bird box of the Griesbaum type, there are
at least two people who are experts in the repair of them. One is Moe
Goldy in Port St. Lucie, Fla. <email@example.com>. The other is Ray
Lins in Burnsville, Minn. <firstname.lastname@example.org>.
After Karl Griesbaum's death, the Griesbaum machinery and stock were
sold to Siegfried Wendel, Rudesheim, Germany, who now makes whistlers
rather than bird boxes. But Siegfried may have parts that would be
useful in bird box restoration.
