bigwull, having been on this forum for many years...I have come to know that many people stop short of typing out everything. They know in their minds what they want to say and don't realize that someone reading without the same background/state of mind will not understand. This happens all the time in the world, texting, etc. So the end of Czechoslovakia (by name) in 1992 was correct in dating a piece made there - because country marks change.
As for 1993...I made an error...a slip of the finger and meant 1992. My bad.
