German inventor and gunsmith. ALS in German, signed 'Wilh. Mauser,' one page both sides, 4.5 x 7.25, December 23, 1878. Letter to a friend. In part, 'As far as it was possible for a first attempt, I have succeeded in Petersburg as much as I could have wished for and, undoubtedly, the commission for a delivery will follow shortly. The widely expressed favorable opinions about the revolver were most gratifying for me, and these were satisfactorily confirmed during the testing period. I have not been able to discover anything about matters pertaining to the revolver here, and so I am completely in the dark about it and I don't know where I stand. You would oblige me very much if you would clarify this for me.' In fine condition. COA John Reznikoff/University Archives and RRAuction COA.
