I own a set of Gretsch drums from the mid-eighties and I love pretty much everything about them, including the design of the lugs. I'm currently in the process of building a second set of drums from the ground up (I build my own stave shells) and part of that process involves acquiring all the hardware. After reviewing practically every lug design available on earth I concluded there was none I liked better than "vintage" Gretsch, so I set about (slowly but surely) acquiring old used Gretsch lugs off of eBay. What didn't occur to me was that although the lugs from the various different eras (mainly 60's Round Badge, 80's stop-sign badge, others?) might LOOK the same, they might also be very different. I seem to have discovered that minor detail just today when I took delivery of a small batch of "vintage" Gretsch lugs and they were different from all the others I've acquired in several fundamental ways.

Sticking with just the larger bass drum lugs (for the purposes of this conversation), what I have (and have been acquiring up until now) measure just under 1-1/2" in length, are about 15/16" in width, and the screw mounting holes are 1-11/16" between centers. They are also "self aligning", meaning that the screw mounts protrude from the lug and fit into holes in the shell.

The lugs I received today are slightly longer (about 1/32"), fatter (1-3/32" wide), have a much shorter distance between centers on the screw mounting holes (1-3/8"), and the lugs are NOT self-aligning (the screw holes are flush with the bottom edge of the lugs. Are these "Round Badge" vintage lugs?

There are other disparities as well, but mainly because of the size differences I clearly cannot mix and match these two different styles of lugs on the same set of drums. Ruling out the newer modern (overseas) lugs that Gretsch is offering these days, are there any other variations on "vintage" lugs I need to watch out for?
