i've often wondered too. . .
By the way, he was born prior to DS and he was named from a Burt Reynolds TV show character named Quint...
missed the quintessential element. .
Hmmm... It looks just a little different from the cane on the show. It might be a little taller if it isn't the exact one from the show.
Also, JK once indicated that at some awards (perhaps the Emmy's last year?) that Quentin T came up to him and said, "Mr. Karlen, I love your stuff."
Jonathan Frid still has his cane from the show, but none of his costume. When DS ended, he kept the cape, a ring and bought one of his suits (the brown one, I think). His secretary threw out the ring and cape during the 1970s, and the suit was eventually auctioned off at a convention, I believe.
