Very cool, it looks like yours is a '77 bases on the info below in quotes which is from fellow TBer and all around great Jules website
http://www.flyguitars.com/gibson/bass/
and Gibson.
If I understand it correctly yours would be '77 production with decal S/N instead of a stamped date - making it an interesting bass. Yours is far, far better preserved than any of my three examples, two of which have broken headstocks, and are refinned and the third likely off to the paint shop later this year.
Thank you for sharing your pics and video, nice chops!
"During the period from 1975-1977 Gibson used a transfer that had eight digit numbers, the first two
indicate the year, 99=1975, 00=1976 and 06=1977, the following six digits are in the 100000 to 200000
range. MADE IN USA were also included on the transfer and some models had LIMITED EDITION also
applied. A few bolt on neck instruments had a date ink stamped on the heel area.
In 1977, Gibson first introduced the serialization method that is in practice today. This updated system
utilizes an impressed eight digit numbering scheme that covers both serializing and dating functions."
