Info needed: Early mirror arms

[Jordan Baker]

Just measured up mine. The end diameter where the mirror goes is 1/2. But the rod tapers up to 11/16 at the base end. It’s a pretty consistent taper. The 13-1/2 is correct

Why would they taper (counterintuitive to wartime expediency) and how did they do it? Are these cast? It makes them hard to reproduce.

I don’t know why Bruce....but they do. Yes it makes it very hard to reproduce. There is a small line that runs along the length of the rod portion. So either cast or forged.
