It is easy to be taken in by this seller, since he uses the term "Seitenschloplatten" (sidelock plates) where, of course, there are no sidelocks, only dummy plates for engraving.

The irony is that the drilling is unique without the misinformation. The bidding seems to be going ballistic with 20 days still to run on the auction, so I suspect that misinformation has contributed to the enthusiasm.
