I think Taylors & Co first released the "Comanchero" rifle in about 2010, and it's still being issued. Does anybody know if there have been any changes to the "model" since it was first released? Would the one they are making today be exactly the same as the first ones made - or have they "improved" anything? I have the opportunity to get one that was made in 2010 or one that was made in 2011. Both are new in the box. Is there any difference?
