I'm not sure on this but let me have a go at it.
The heater and everything you show in the photograph appear correct for 1941 except the switch. I'm not so sure the brass (or whatever material it was made from) heater cut-off was original.
The heater is not the super deluxe but the next one down. The super deluxe had three bands instead of the one as yours has.
As to the switch, it is my understanding that the 41 heater, defroster, fog and back-up switches were a sort of tan (and closer to the pink used on the 1941's lower dash color) instead of the darker browns used from 42(?) and up to 48. I think it was Gene who pointed out the difference here on of the forums some time ago.
I would expect that the heater and defroster were hooked to the dead side of the ignition switch and received juice only when the ignition was on as when the engine was running. Not sure about that though.
What I am sure of is that now that I have replied that others will feel compelled to give you better advice/opinions than mine. Just saying.
Good to hear from you again.
Best,
Charlie

BTW: Nice try on the missus

forgetting things you have done to upset her. They never, ever forget but instead have learned that as time goes by: what is the use of bringing it up? Or something like that.
