Non-Day/Night Rearview Mirror

[MoparCarGuy]

I have this extra rearview mirror (picture 1). It is Non-Day/Night. No Day/Night switch or any markings on the mirror glass showing "NIGHT    DAY". I owned a Challenger T/A in the 80's and it may be from that car.
What do you know about the Non-Day/Night mirrors a.k.a. non-prismatic rearview mirrors?

The mirror in my 1970 Cuda is the second picture and I believe it is correct since my Broadcast Sheet shows G41 for the car.

Supposedly these were used in the lower price line models like the Challenger Deputy or Barracuda coupe with the fixed quarter windows. That said I seem to have one laying around too and it would have come out of one of the '70 318 Challengers we parted out over the years, neither was a Deputy though. 

Edit:
apparently also 70-76 A Body and 72-74 E Body
