The base plate and top cap are made together as a unit for each order as has been said on many occasions, James will not sell 2 or more base plates with a top cap... Its strictly 1/1 each order...Also, it sounds like the Maker really does fabricate these "to order", and doesn't bang-out 100 WR2 plates to keep in-stock proactively... so not much opportunity for supplying the wrong plate to an Order.
