I'm new to the forum and new to drums (well, not exactly. I owned and played a set of Whitehall drums back in junior high in the '70s, but I think all that does is makes ME vintage!)
I have what I believe is a 1968 Ludwig Supraphonic 400 snare drum. It was my brother's drum and I got it after he passed away about 5 years ago. It's gone largely unused up to now and I decided to clean it up and see what I could learn about it. Though I have just started cleaning it, I have learned a few things, and certainly a bunch of it from this forum.
So far, my research has shown that it's a very popular snare drum, and has been for many decades. Dating it has been made easy for me with a date stamp of September 25, 1968. The keystone badge has a serial number that corresponds to the serial number charts for that era. It has "A-G" stamped on the inside of the shell, which also seems to be typical of that year.
The interesting thing that I found, is that the A-G stamped on the inside of the shell has a bit of a misprint. The "G" is printed upside down in relation to the "A". Have you ever seen one like that before? How rare is it? Does it add to the value of the drum? I've attached a couple of pictures for you to see.
I'd love to hear your opinions on the drum and the "minting error".
Thanks,
Mike
