Thank you for all the input , interesting to note that William Palmer Jones is credited by many to have been the inventor in 1889 .
William Ford , barrel maker to W.W.Greener I believe made a trygun in 1870 so he may have been the actual inventor.
I also recently learned that W.P.Jones may have actually patented many inventions and ideas that were actually those of William Baker 1858 -1932 of 7 Bath Street Birmingham.
