Here's a method that duplicates the cast builders plate - use a PCB etching kit from Radio Shack. Other materials needed are brass sheet, dry transfer letters (Woodland Scenics), paint, and clear coat.
1. Anneal the brass sheet.
2. Paint the back of the brass sheet and the edges.
3. Scuff the face of the brass sheet with a green 3M pad or fine sandpaper.
4. Layout the plate using the dry transfer lettering and striping as appropriate.
5. About an inch from one end of the plat, bend the brass strip up as a handle. Cut the upward handle about an inch long,
6. Follow the instructions for using the PCB etching solution (ferric chloride).
7. After etching to the depth you want, clean off any etching solution. Trim the plate to the proper size.
8. Polish the raised lettering and attach to your base. I've painted the etched area black or used A-West Blacken-It with good results
