No I have not. Years ago a query to Mr. Jinks about a rare pre model 21, N frame .44 special was so worthless as to put me off paying for letters from Smith and Wesson. They could not tell me where it was shipped or production date and just gave me the dates of production of the model and roughly 1200 were made. Heck, I already knew that much... However the 1899 being a military contract gun might be worth the bother.
