Decorative Photo-etch mesh sources?

[Spex84]

I've had little luck finding sources for decorative photo-etch mesh so I thought I'd ask here. It's relatively easy to find photo-etch packages targeted towards specific kits, and generic radiator mesh/round holes/diamond holes etc, but I'm looking for something more like a vintage heater box, or the below photo of cupboard doors with patterned perforated metal. I swear I saw something like this on a scale model in the last few years...

I have a '50s hot rod model in progress with a round-hole mesh grille made from a coffee strainer...but I'd like a more mid-century-modern pattern if possible:

You can try a model RailRoad site for this mesh. I used to see this stuff at George's Trains in Toronto when my dad was still around and into model RailRoads.

Thanks Douglas. I'll keep looking!
