I thought that was a Gretsch thing?

I see them on 50's Slingerland toms quite often, but don't know when it changed. It's the same muffler you see in a Radio King snare. I'm trying to date two no-badge Slingy toms, the date stamps are not readable, but they have three holes for the double muffler mounting footprint...

I was thinking one for the resonant head also. Sorry.

No, Lucky, my mistake... I wasn't clear...

But yeah, I need an era-correct bass drum to go with the 9x13 and 16x16. The bass that came with this "kit of shells" is a 12x22 dog tag, so neither of the toms really go with it. The Ebay seller "mis-quoted" the size of the bass, so now I'm running an orphan farm until I find a bass for the two. I did get the double-headed mufflers that came off the toms gratis when I contacted the seller about the mistake. I can make one of the Ensemble kits from the mid-fifties with the 12x22 fairly easily, and I got a killer deal on the three drums to begin with, so I'm not too upset about the whole thing.

So, anyway, I guess my original question still needs an answer....

Thanks in advance, all!!!

Not sure about the mufflers, I would think late 50's. I am trying to put together that same kit. I have the 13" tom but need the other two pieces. Good luck on your journey.

Thanks, Lucky, you too!!
