John...I have researched many revolvers in the pre-war records and read many pieces of correspondence. However, the information does not provide an answer to your question since there is really nothing pertaining to when a revolver was made, only when it was shipped. In some cases the time between when an order was received and the guns were shipped is only a day or two (guns in inventory), but sometimes it is several months meaning the guns were out stock and had to be manufactured.
