Nice drum!

Is the finish on your drum Factory?

It looks somewhat the same as mine.

And....4moreyears....here are the photos you asked for:

the grommet is just pushed into the grommet hole - easy to remove

the shell is 3/8ths FOUR Ply

Here's a closeup of the strainer.....just like the one on the cover of the 48 Gretsch Catalog in the link I provided above.
