Hawg, how are the castings in your older Piettas? Did they take the time to mill or file the roughness after the cast, or are they used the way they came out of the mold?
I heard somewhere, don't know how true, older Piettas weren't as good as more recent. Thoughts?
You may very well be correct about mark, but wondering why that has to be a manufactures mark as opposed to an import mark.
If I wanted to I could place an order a certain brand of guitar from japan, tell them what I would like different to save cost and have them put any name I want on the headstock, have them shipped and sell them here. They would still be that companies guitar even if it had my name on it.
Sears, as an example has done that forever.
Got to looking at that PR stamp in your pic as well. 'C' for 'conical'? lol
Again, you may very well be correct, probably are. I am still researching, no solid conclusions, and it really doesn't matter to me what it is. Just like to know what it is. And thank you for your input.
