I'm tempted to take him on, sending him an email from an "unnamed famous Luger collector" looking for the second of a consecutive pair of AH signed Lugers that were presented to Alois Matzelberger in 1938 by AH himself.

If it were the second of the pair together they might be worth half a million.
