Looks like the main part is a Ludwig P83 and the slider from a Slingerland Rapid strainer.

Thanks Thin shell,

You are right on, I couldn't find what the slider came from and did not know but of course the knowledge here is amazing and I do believe you are correct.

It is currently on a 60's Camco 10x14 snare.

Thanks again,

Wayne

+1 with thin shell. Slingerland used that three hole slider for more than three decades.

Thanks slingerfan,

Just goes to show you how much I know.

Just a guess on the purpose of the center hole... Bring the ends of the strings from each of the outside holes through the center hole. Then, tie the knot to join those two ends in the center of the slider

Leedybdp,

That was my guess too!
