I have to agree with Chuck, that is first class workmanship. Did you make the Borchardt rear sight? I know how they are made, it's easy when you know how, but if you don't it causes a lot of head scratching. lol.
I understand from an article I read that C.Sharps borrowed the original rifle to back engineer it, so they are the only ones likely to have plans. Joe Lozito MAY have got his plans in one of two ways, He could have purchased a C.Sharps copy or measured the only other existing action.(that's all there is of another).
Has anyone noticed that if the tangs were straightened on the action and the hammer and lock mechanism were removed,then you have the profile of the 1878 Borchardt. I wonder if he designed the '75 model as well?
I am not aware of anything on the 1875 in the Public Domain except perhaps a Patent. Sadly, I have never seen a Patent Drawing with dimensions. Nearly all of the plans for US single shot rifles available on the www were drawn by an ASSRA member who reverse engineered them from original rifles. The Borchardt plans were not done by him but another company (There are a lot of errors in the 1878 drawings, I know, I've nearly got mine finished). I've been away from my machines for nearly a year on Doctors Orders but I'm modifying my Mill at present and should be making chips again before Christmas. Virtually all the plans on the www and Fleabay are copies made from sets of drawings available from the ASSRA Archive for 10 bucks per set.
They are A4 size but enlarge beautifully to full size for a few dollars more at your local photocopying shop.
Good luck in your search but I think you may have problems getting plans. I think perhaps you may find it easier to find a crock of gold at the end of a rainbow.
