Hi, I've got an old Premier Royal Ace piccolo. COB I think and it's missing one of the washers that hold the offset lug onto the metal shell. It's a hollow spacer washer that is different to the washers used on the wooden shelled Royal Aces. Just thought I'd post in case anybody had one? Any help much appreciated as I love this snare and would like to get it back to tip top condition.

Many thanks, Graham.
