I couldn't remember if I had posted this over here or not? So here goes:
I restore the early heater panels and ears if anyone needs that done. I bead blast them, then powder coat them in the wrinkle finish, then I hand screen print the lettering on the face of the panel. All of this for $65.00 plus shipping back to you. If you would like to look at some work I have done check out this thread at MM forums:

Those look really nice! How do you do the lettering?

 

Screen print the lettering by hand!!! Olde world craftsmanship!!!

 

This is just a shot in the dark but can you do anything with the later style heater boxes. I have a perfectly good heater but the front face is missing. Dion at Dj minis was going to look for a decent one but I don't think he was able to come up with one. I guess its a little different cause its plastic.

 

I do mainly the early type heater panels. I think the ones you are referring to are a curved type made of plastic? Wish I could help. I have a complete old heater that I am getting ready to restore. I already have the panel done, just need to do the rest. I powder coat that too. I do need some " ears" for it though.
