One other option if you're Photoshop inclined - what I've been doing is to scan the original and use Ponoko.com to laser-cut a reproduction from cardboard or hardboard (depending on the original thickness).

I described the process here:

I've created grille cloth boards for:

• Philco 16B 'shouldered' tombstone
  
• Philco 16B 'peaked' tombstone
  
• Philco 45C
  
• Philco 70/90
  
• Philco 37-650B
  
• Philco 37-2670B
  
• Silvertone 4565
  

It also works for missing radio backs. I've made those for a 41-226C and 48-225 so far.

Yes - it's overkill, but maybe if it's interesting to you it's a fun related project in its own right.
