The shaft that holds the tom and the floor tom legs are 10.5 mm. I found what they're called in a catalog, but forget what it was now.The tom holder with the red sticker looks like a Ludwig Rocker LR255STH single tom holder with the 9.5 mm L arm tom holder; I can't tell you the time frame of the drums, sorry....
That's a Ludwig Single Tom Holder. It's also distributed by Gibraltar. If you opt for the 10.5mm L-arm, it will be a direct fit.
Not the serial #'s on the badge.I just posted about it in another thread: https://www.drumforum.org/threads/ludwig-current-serial-s.128394/page-2#post-1994629
Yes - weird indeed. I had some doubts at first, but after considerable research, I'm convinced they're legit,That's interesting.
I think that's the first time I've ever heard of a Classic Maple shell that wasn't date stamped.
Not even the paper tag that I think they use now.
