Seems like the exercise would be a learning moment for a gun shop owner wishing to expand on his knowledge base. Knowledge is power.
Just as an aside..there is a very good tutorial over on Jans site on bakalite grips. I used it recently to authenticate a set of black grips. AFTER I tried the pin test to tell me they were genuine bakalite. Once I had that figured out..I spent an hour studying to tell me everything I wanted to know about the type. Just SEARCH black grips and you will find it.
