akjeff;
Have you looked at ".22 Caliber Varmint Rifles" or "Woodchucks and Woodchuck Rifles" by Landis? He covers quite a number of gunsmiths of the era.

akjeff;
            I have information on Albert Hartung, he lived and died in Pomeroy, Ohio where I went to high school,about two miles from where I live. Hartung was the local gunsmith-gunmaker, he used a lot of Mossberg barrels plus making barrels with his own rifling machine. the .219 Zipper was one of his favorite cartridges.
PS  -  if you have any questions about Hartung  I'll be glad to try and answer them--take good care of the Borchardt----leadball

Thank you one and all! 

leadball, I've sent you a PM, thank you very much!

            Ebersbachs Hardware store was a meeting place on Sat. night in Pomeroy OH, Mr Hartung would be at the center of converstation, always about rifles. This was back in the late 40's & early 50's, Mr Hartung talked about such things as .219 Zippers, 22 Varmiters. & .219 Wasp, we had no knowledge of these calbiers but we listened because Albert Hartung was THE rifle man for a hundred miles in any direction.
             The .219 Zipper was a favorite. many 22rimfires with Mossberg barrels,  many Mausers and Springfields and I have been told [never seen] that he made about 12 custom shotguns. The singleshots were mostly High Walls in centerfire and Stevens 44 was his favorite with 22rimfire. There are a few men left in the county that knew Albert much better, I knew him through my father because they both loved rabbit dogs. if you wanted Mr Hartung to work on your rifle, you started talking to him about rabbit dogs.    leadball
