For any of you folks still following this exercise in futility, from the mid to late 1800s, and possibly earlier, gun makers in the tube trade had the term "Rohr" attached to their function. So a "Rohrschleifer" would be a barrel grinder or emouleur de canons de fusil(French). While a tube finisher would be a "Polirer", a fine borer or finishing borer. The Werner and Wagner folks were big into tube making so the stamp with a last initial of a "W.", other than "J.W.", would more than likely be for either one of the Werner or Wagner klan. From the mid to late 1800s the following had the listing of "Polirer":

Gottfried Wagner
Theodor Wagner
Christian Werner
