These were purported to be original drawings of the Navy LeeAttachment 40290Attachment 40291
I got them as sort of gift from the dealer from whom I bought my Lee.
These are what we called reproducibles where I used to work, though they are not the plastic we used to use, of course.
They are in such good shape that I doubt they are originals. One is in two colors of "ink" though.
The nomenclature is really interesting, as that must have been what Winchester called the 1895 rifle. "Lee Rifle US Navy Small Arm"
