Spelling is correct for all panels.

Second panel right side mystery word (for switchs 13 & 14) is "Off".

Mystery word for switch 10 might be "stwd'ss" (abbreviation of "stewardess")

I have to wonder if the panels you're looking at aren't from the DC-3, which might have had slightly different systems than the C-47.

Will take a look at let you know.

Was Googling to see if I could find any contemporary shots of the panels and the following images does share quite a few of the same details from your manual scans, but being as it is taken from within a restoration the usual problems of accuracy do apply.

However this is a Canadian paratroop ship, and the first officers panel reflects this with the three jump light switches.

No.7 it looks like you've written PILOT instead of PITOT as in the combination of No.s 7 & 6 are:

No.s 4 & 5 should be:

I think No.8 should be (there may or not be a hyphen in de-icer, as there does not appear to be one for No.3 but it hard to tell from the image if there is one in the spelling for No.8)

For No.2 there should be a full stop after the word PROP as in "PROP."

No.4 the CARB. DE-ICER switch on the second panel has an extra 3 or 4 letter word ending in OM. befor DE-ICER that I'm still trying to work out.

Looks like it's MOM. as in an abbreviation for a momentary switch:

No.s 13 &14 panel two the centre word is OFF:
