The BSS was made from 71-88 in 12 and 20 guage. Barrel markings were originally (in order). "Made in Japan" followed by "Made in Japan and Assembled in Korea" and finally "Made in Koera from parts made in Japan". The 20's were all 3" from inception in 1972. A 3' 12 guage became available in 1975, when the 30' Full and Full guns were first introduced in 1975. Afterwards, only 3" 12 guages were made ( idlelock 12's were the exception). It was given a a selective single trigger when the sporter model was introduced in 1977-1978. In the early 80's the pistol grip had a single select trigger. Production became to expensive in Japan, so Miroku went to a less expensive labor source. You will need to call Browning, that sn does not follow Browning numbering.
