In response to JDM’s previous question on this thread, here is preliminary data from the 86 Kentucky double rifles I have documented so far in my ongoing study for eventual publication. I am responding to his impossible-to-answer question of how many full stocked flint swivel breeches are out there.
Kentucky double rifles studied to date: 86
Swivel breeches: 68 (The rest are SXS, superimposed load, and fixed O/U)
Originally made as flintlocks: 24
Converted to perc: 12
Reconverted to flint: 9
Full stocked: 20
I find it hard to believe that only half the flint swivels were converted to percussion. It can be difficult to tell if a reconversion is very skillfully done. I have not yet looked deep into barrels for welded touch holes, but I expect my soon-to-arrive bore scope will be helpful in that regard.
Originally made as perc: 44
Retroverted wrongly to Flint 5
Full stocked 15
This sample is not random. There are far more unstudied (by me) Kentucky double rifles “out there” than I will ever find and be able to examine. But I am still at it and hope to add many more before going to publication with my findings about their evolution in America, mechanical innovations, function, and history.
I am seeking leads on double rifles for a trip around Pennsylvania this coming late June (KRA time), and around Kentucky, Tennessee, Virginia and surrounds in August (CLA time). If any of you can help with that, my efforts will be improved, as will the eventual finished product.
