Is it a 1.75-6x32 or a 1.75-6x40, which I did not know they made?
I wondered the same, but I think there was a predecessor to the 1.75-6x32 known as a short model. His measurement of 10" agrees with that too. Also, the objective "flare" looks more abrupt than the 32mm objective. Might this be a Vari-X III instead of VXIII, or did they carry it over to VXIII and discontinue it later? I have a couple of VX-III 1.75-6x32's they are 11.1" long.
