Source and/or name for this perforated craft metal sheet?

I'm pretty sure it's a scale model version of industrial slotted hole perforated metal sheet, but I can't find anything, craft or otherwise, at this small a size. M-D Hobby makes a number of patterns for craft & hobby, but none like this. It looks like brass to me..

If anyone has any ideas where to find some, I'll be much obliged.

I believe it was harvested from an acid etch metal detail sheet used to add super details to existing models. Mostly ships.

Good suggestion! It's not identical but I found this car exhaust manifold that's really close.

I've bought similar stuff at hardware stores like True Value and Ace Hardware. Usually it's rolled up and inside of a clear plastic rectangular "tube". I'm not sure if they'll have that exact pattern though.
