1940s Welch Allyn Otoscope Speculum

For Welch Allyn otoscope, manufactured somewhere between 1930-1950.

I figured I'd take measurements of my otoscope specula since they'd be quite hard to find if I ever lost them.

This is a slightly modified model of the longest speculum in the set (this one has a larger shaft). If there's no elephant footing, it should be able to fit in the holder ring right after printing.
