Not sure what you are looking for, muntins and mullions or a grid pattern? Try Rockler or VanDykes

best bet is someone with a scroll saw to cut them out, if they are the style I am thinking of, or maybe this place.

Thank you both for your ideas. I just contacted a furniture maker that makes secretaries, and they recommended a certain laser graphics company. I'll contact them and see if they can do it for me.

Most of these I recall are made from 3/16" plywood, in a veneer matching the main casework. If it's important to you to match this, you will probably need to special order that material, as 3/16" walnut or mahogany plywood is not usually stocked. If staining is alright with you, then you can use ordinary birch plywood.

I had a carpenter make them for me.
The original grill insert was flat and I wanted a raised panel.
He used the flat one as a template.
I then stained the grill to match.

Instead of contacting the laser company, I called a furniture refinisher not far from me in NJ. Just as lsst said, he'll use my old ones as a template to make new ones.
Thank you all.

Hello, I have the same situation. The wood grilles on my secretary are beyond repair. I am having a hard time finding someone to make new ones. Could someone share the contact info for a woodworker?

I need someone for this as well. Appreciate any suggestions

Did you ever locate options? I’m having the same problem.

same here . i refinished an old desk years ago but it had no grill over the glass cabinet doors. id like to find ones that fit. i though of making them
