Help Dating A Bottle Of Johnnie Walker
 

hello, i thought i posted a thread before but it didn't show on the forum so i am not sure what happened. Anyway i am trying to date a bottle of Johnnie Walker that i purchased in 1993. It is still sealed, it does not have the serial number on the back of the label that i can see. I was hoping i might get some help?
the bottom of the bottle reads:

SC924
71mm H (symbol is an elongated H not an actual H)
Liquor
Bottle
Scotland
48 U8 (not really a U but a horseshoe)
JW

any help would be appreciated!
