I knew it was a long time ago. I got one. . it appears. . .for Post # 800 but there where no rings is stock and I got it sometimes later. Maybe Tom still knows.
Anyhow, after receiving the SDR I tried to unlock the secrets of the stock market. I discovered this
1 Buy Low 2 Sell High 3 Go To 1
It Works!!!!
I made a lot of dough with it but lost it all and more on an engineering venture :-(
Several years ago I lost the ring. . .no wonder I no longer know any secrets these days!
