Must drive the professional smiths crazy dealing with this stuff on a regular basis.

What helps us is that we usually have very good knowledge of exactly what we're askin' for. In my case, I have a full set of most makers' parts lists so I can specify the exact part number I need.. Saves the idiots from attempting to decipher what a customer is askin' for.. Most firearms owners that I've run into have no idea what to call a certain part. And it DOES take a while to learn the proper name of every part..
Only rarely will I get a wrong part in - maybe once every two years.. Guess I've been lucky..
