These are not a dime a dozen that is for sure. I know they are out there and I have probably seen less then 5 so far in collections.

The only issue with this one is that the factory had drilled a standard butt side on it (2 extra holes) then it looks like the Radio King Hardware was added.

You can't see them from the outside of the drum because they are covered with the hardware.

If the drum was a retrofit then more then likely the strainer side should have had extra holes also? They never made a drum with a 3-point on one side and a standard butt on the other side.

So that is why I think it was a factory error.
