Date this Bonney socket?

[NoahG]

Can anyone give an approximate date to this Bonney socket?

1/2DR, 12pt, 31/32", marked "A31 BONNEY" with the Circle CV logo.

(Ralph was my grandfathers name, curious as to when he bought this)

I'm married, else I might consider dating Bonney.

I was just thinking, "Well, if she is cute enough, maybe."
