I have a lufkin 1641V for sale, or trade.
I got it in a vintage Kennedy machinest chest and it appears to have extremely low use. I do not have any means of checking its accuracy but once again it appears to have extremely low use. I have no reason to believe it would not function as it should.
I am asking 30 dollars cash shipped to the 48 states, or trade for perfect handle wrenches and drivers.
To my knowledge the best way to ship delicate or sensitive items is to put in plastic wrapped in a bit of newspaper, then surround it with expanding foam. If you have a better way please let me know.
