It is being represented as a 60's era Ludwig. It has a keystone badge serial dating it to '66.
It has 20 lugs, and is 15" deep, 16" wide. Pulling a head, I found that the badge - is held in place with a fold-over type clip/bushing, visible in picture. There is no muffler or mount for one. There's no reinforcing rings. No date stamp.
Could it be a later Ludwig? Or not a Ludwig at all? The lugs are regular type you'd see on a '60s Ludwig, no extra holes anywhere.
Amazing...any idea would be appreciated.
Thanks!
