R11 Music Master AM radio question

I'm having a speaker reconed and I pulled out all my cores.
how is this for veriety


#1, #2 and #5 have the same text
#3, #4 and #6 have the same text
#1 and #2 have the same frame
#3, #4 and#5have the same frame
#6 has a unique frame
#1, #2 and #5 have the same terminal backer
#4, and #6 have the same terminal backer
#3 has a unique terminal backer
#3, #4 and #6 The text looks like the text in the OPs photo in post 1, just really hard to read in the photos

Not much left of the fronts but all the intact Voice Coils are all 8 ohm

Lastly

#1, #2 and #5 have MAYBE a date code on them

Day 807 is Sunday, October 13, 1963
Day 825 is Thursday, October 31, 1963
Day 738 is Monday, August 5, 1963

all of these speakers were said to be from 67 - 70? A bodies so it doesn't seem likely that the 3 digits are a date codes
