Lots of the late 1990 and early to mid 2000 cent DDRs you generally come across are unlisted. I've got hundreds. So if you can't find a match, it's most likely unlisted, especially ones this minor.
Still a good find though!
"Life is like a box of chocolates, you never know what you're gonna get." - Forrest Gump The concept of maturity is complex. While one's capacity to be mature can be correlated with age, someone's overall maturity and respect for life is not. Maturity is formed through experience and perception. Human progress can only be achieved through trial and error.
