My evidence that the PL-259 was not prewar:

The patent you gave was filed 12 AUG 42 (USPTO).
The Navy issued the type number 28 AUG 42 (NAVSHIPS 900109 catalog).
The PL-259 types do not show up in Amphenol catalogs until the 1943
edition (various Amphenol catalogs).
The 1939 edition of the Signal Corps SIG-5 only goes up to PL-125
(actually, pre-SIG-5 "official stock catalog").

I think the Amphenol catalog may be confusing the PL-259 family with
the 93 family. I would not trust it.
