If you have some wood working skills you could build your own. Or, if you know someone who does you might be able to have them cut out the the shape you want and you could finish the carving yourself. I couldn't really find anything I liked for my Model 12 either, so I decided to see if I could just make one myself. I am a novice wood worker and it really wasn't all that difficult; band-saw, hand plane, some chisels and files are all you really need. The nice thing is you can make them exactly the way you want them and have the satisfaction of producing something yourself.
