I have a white (now yellowish) marine pearl snare drum

1 ply map with rein hoops map

8 lugs

DATE stamp of July 2 1958

however it has a rapid strainer and a butt side?

There are 3 holes on the rapid side, ONE big one on the top and two small ones at the bottom, together forming a triangle.

and the butt side has the same thing, except the top hole is the same size as the bottom two. And are less separated

And the snares themselves are split up... 6 wires then a space, then 8, then a space, then 6 again. forming 20 total.

The badge is gold with the swoop on the S, no serial number made in Chicago.

What is goin on with this drum??? is it a fake?Help2
