Ok boys and girls, it's time to hear your best guess on these extra lug holes as the owner and myself absolutely do not see eye to eye on the what and why.

A friend of mine picked up this early 70's Slingerland set and discovered these extra lug holes under the orgional bass drum lugs. You can clearly see the inside hole of the orgional Sound King lug has been crudly roughed out larger and someone drilled a new hole in the center for a shorter lug. THEN they sloppily filled the new hole with putty. The outside factory hole appears to be unmodified.

Because there is no discoloration around a small lug profile (only around the larger factory profile), he is convinced someone at the factory drilled the drum for tom lugs, then realizing the mistake, drilled it for the correct size and filled the wrong holes with putty. I say no way, that was done by a future owner due to the inside or inner factory hole being enlarged and the sloppy putty. No factory worker was going to spend that much time and energy covering up a mistake when there were dozens of shells at thier disposal.

While I am an admitted Slingerland fan boy, I also acknowledge that they did not have the tightest of quality control standards. HOWEVER, I say not only would they not have made that mistake in the first place, if they did, they would have simply tossed the shell and grabbed another.

I told him I consider myself a Slingerland expert... but only in the things I know. The problem being I know very little! So I asked for a few pics and said I would post them here, asking the opnion of true experts.

How did these middle holes get here.... at the factory (booooo) or later, added for a smaller lug (which I admit makes no sense) by a future owner (yeah!). Weigh in with your thoughts and I will share with my friend.

I'd say factory screw-up. Considering the fact that I just totally disassembled a Ludwig kit that I bought brand new in factory boxes back in 1979, only to discover one of my rack toms had a tension rod shorter than the others, I'd say anything is possible coming out of the factory. I could be wrong, but I'm willing to bet they just don't throw away good shells at the factory just because of one or two wrongly drilled holes. Shells are costly! You and I might have wanted to toss the shell and grab another, but the manager at the factory where these were being assembled might have been told otherwise...meaning: "fix it and make it work...we're not wasting a perfectly good shell". The reality is, your friend will probably never know why this has happened, but can only make the best of what he now has. The nice part is the defect is hidden under a lug. I wouldn't sweat it.
 
I’ve bought and repaired a few Slingerlands.
Your assessment is correct. They drilled one of the original lug holes larger. Why the middle one is there at all I have no idea as the screw spacing between middle new and either old hole is too short for most BD lugs.

Slingerland quality control was pretty good in years 1950s to 1970. Most of their bearing edges were better done than many Ludwig’s.

Are the extra holes under one or two of the lugs or all the lugs? What is the center to center distance between the "outside factory hole" and hole in the middle? What size is the bass drum? 20? 22?

All of this, PLUS: Do the holes align with Slingerland's smaller tom lug? If so, I'm saying it's factory. Someone put the shell in the wrong jig.

The extra holes only appear on the 22" bass drum and they appear under each of the 20 lugs. And yes, the center hole indeed matches the footprint of the smaller tom lugs.

One tension rod shorter is way different than extra holes ……
No way Slingerland did that .
