Dave, it is well known, that you mean that you only collect 110s. But your knowlege at other Bucks is mostly a lot better than others who collect not only 110s - like me.
But to your question:
The material of the scales makes the difference between the second, third or fourth version of the 112. And if they are made of ebony the knife is from the fourth Version, that's all. I don't know, witch one is made oftener than the other. Does anybody knows it?
Best,
Haebbie
