Recently I picked up a significant amount of miscellaneous vintage drum hardware. Some of the pieces were vintage Ludwig and Slingerland parts. Others I'm simply trying to identify. Among the hardware were the casings you see in the pics I've attached.
The larger pieces (1st three pics) are approximately 3.75 inches in length and the distance between the holes is approximately 3 inches. The smaller pieces (last 2 pics) are approximately 2.5 inches in length and the distance between the holes is approximately 1.75 inches.
These pieces look very similar to Slingerland's vintage streamlined lugs but I've got a feeling that they're simply some Japanese copies. Can anyone out there confirm this?
Thanks!
