From the Buffalo Bill Center of the West, McCracken Research Library digital collection, WRA Co. drawing collection here is a copy of a drawing from Deutsche Metallpatronenfabrik (D.M.), dated August 2nd, 1894, drawing No. 426.
I assume this drawing is showing an early version of the 6mm US Lee Navy, is this correct?
Included in the pdf below is a screen shot of the drawing in its entirety and then screen shots of enlarged sections of the drawing to provide better detail.
Any corrections or additional information are most welcomed.
