The “B” after “LM402” indicates that this is a NEW B-Stock drum. We carefully inspect and tune every drum before offering it for sale. Generally, some insignificant cosmetic flaw earns the “B-Stock” designation. Of the over 100 units we’ve sold, only one or two have had noticeable flaws of any kind.
This particular batch of drums is different than we usually see. They feature Keystone badges and serial numbers (as opposed to cut Blue/Olive badges and no serial numbers). There is an “X” lightly scribed into the internal side of each shell (see photo). Overall, this is the cleanest, least flawed shipment of B-stocks ever offered through our store.
