Hello all,

If one of you are fortunate enough to have a Slingerland DuAll snare with the center rod mechanism (like the Super Ludwig patented version), I would appreciate knowing the following dimensions:

1. spacing between the the two horizontal screws that mount the DuAll mechanism bracket to the shell.

2. vertical distance from the horizontal line between those two holes and the hole used for the center rod of the snare mechanism. Preferably for a 5" drum.

I'm curious to see if the mounting hole pattern matches the holes in my mystery drum shell.

Best regards,
