Just to singularly note the top-shelf mechanics were who were associated w/ Edgar Strempel:

"The consignor's notes state that Edgar Strempel employed and/or worked closely with 2 of the most famous European engravers- Karl Kolb and Richard Schilling, the well known and sought after locksmith Guido Kessel and the best actioner August Wuelfing. The stock was made by Ernst and Karl Roell. Walter Schilling was the metal finisher/bluer. "
