Hi, I have an old 7 x 14 WFL with the Zephyr lugs. It's missing the tone control, but the holes in the shell look just like a Radio King. There are 3 holes for what I assume would have been a dual muffler like Slingerland used. I have seen these dual mufflers on WFL drums and I think maybe Leedy used them too, but not 100% sure on that, maybe somebody can clarify. I'm wondering if the hole spacing would be the same for Slingerland, WFL and Leedy (if Leedy used them too)
Thanks in advance for any information.
