Question about 1950s acoustic FON

So I finally got a CF-100!
The question is about the FON. It's got features of a '52 or later (pearl logo) with a FON of 6964 4. No letter code, and that extra "4".

What does that mean?:hmm


Thanks in advance.

Found this here, a "Count number" whatever that is?


Gibson Acoustic Serialization
Taken from the 11th Edition
Blue Book of Acoustic Guitars


"1947-1961: Gibson changed their serialization system once they
reached 99999 and decided they did not want to go to a six-digit system.
Instead, they added an A prefix followed by a three-, four-, or
five-digit number. The new system started on April 28, 1947 with
number A 100. The last number was used on February 21, 1961.
From 1947 to early 1955, white oval labels were used. In early 1955,
the label was changed to an orange oval. Serial numbers are on the
label and FONs are ink-stamped on the inside back of the guitar.
FONs consisted of a letter, four-digit batch number, and count number
(i.e. Y 2230 21, V 4867 8, R 6785 15). FONs were discontinued
after Gibson changed to the new serialization system in 1961."

Thanks. "count number"

No letter code. :hmm

Groovy guitar. Needs some work, but is playable now. Single-line strip tuners on the way. Could use a neck reset soon. Top crack/brace needs work bass side of sound hole.
