Don Francis, do you want some bad news?? If not, read no further. Your Luger has a replacement barrel made in Germany by either Oscar Will AG, Romerswerke AG, or Venuswaffenfabrik on contract from B�¶hler Stahl for the model 24 rifle of the Finnish Civil Guard. It apparently has been cut down to fit the reciever and is probably in .30 cal. These barrels were manufactured from 1924 to 1928. B�¶hler Stahl is still in the steel making business. Additionally it has been completely refinished, probably at the time the replacement barrel was installed, evidenced by the normally strawed parts being blued over, and the lack of crispness of the hump on the side plate and elsewhere indicative of heavy buffing. Take a look at this-
