I have observed nearly all Military dates with Banner toggles. In my collection, I have a 1937, 1938 and 42-byf with Military acceptance and Banner toggles. Each of these pistols seem to be in the last suffix range of the transition to the next date. For example, one is pictured in Jan's Third Reich lugers. 1938 Military in the - n- suffix with a Banner toggle. As you remember the - n - suffix was the transition to the 1939 dated pistol. Is it possible that occasionally Mauser needed a few toggles and some came form the commercial division. certainly worked the other way around very often. Fake? I doubt it.
