The answer is no. The BL22 was introduced in 1970 and had a "70B" preceding the production number. The number changed for each year thru 1976 which was 76B. After 1976 the new system was used and a two letter code was used to determine date. Be aware though, that FN produced and sold this model outside the US beginning in 1956. These were FN guns and essentially the same as the Brownings that were imported in 1970. The markings are different and do not say "Browning Arms Co." on the barrels. It's probable that the FN guns did not have a letter in the serial number.
No set length. It may be letters, numbers, or letters and numbers. The shortest I have ever seen was "1".

I can find no reference that shows Browning ever made a model called the C5.

Browning Superposed Shotgun
Not for commercial sales.
No such model number ever used by Browning.
There are no two "last" composite numbers. Just as with prime numbers, and all numbers, they go on for ever and ever and ever and ever ... ... .
