Its just disappointing that this seller, who has a pretty good grasp on vintage percussion and hardware based on feedback history, couldn't provide additional information about these shells in the description.
I guess if he/she truly has no idea what brand the drums are, then the description provided was okay.
Like others have said, not knowing a full timeline of communication between the yourself and the seller makes it difficult to gauge.
If you asked a question 3 hours before the auction ended after placing a bid, vs. asking a question 5 days before the item ends without placing a bid.
Good luck and please let us know how it goes!
