Hi again, Jurgen!
The chances of posting pictures are pretty slim, my friend. I have not spoken to my daughter's "friend" in many months. I have not even seen where the drums are kept. The chances that he will ever repay me for the loan for his Boleros are even slimmer. That's okay. He has to live with himself.
You know, sir, I think the bottom line is this: If you enjoy these drums and take pride in them, then I guess it doesn't matter too much if they are Star or Pearl. I love the research too but, there are times when definitive answers are impossible to obtain. One "expert" will tell you one thing, another will point in another direction. That's fine. Most people are entitled to an opinion.
Enjoy your wonderful musical instrument, Jurgen!
Brian
