You probably won't like this suggestion but Vintage Gun Grips in Florida makes a "spot on" match for the Model 12 plastic butt plate.........and as a bonus you can get it in a variety of colors including pink but I'm sure you would prefer the standard black one. You cannot readily tell them from the originals, I think their part number is R12, the one used for the Model 14 is R12a and they cost about $20 delivered.
At least this gives you an option, you will have to fit it to the gun but the screw holes will line up perfectly.
Good luck!
