Albert,
As with most forgeries, a fake only fools the uninformed. If you didn't know the exact details of a so called "Portuguese test Luger" other than it has a large two-digit number on the left receiver and were unaware of the proper serial number range you might become a victim. They might be trite statements but "a little knowledge is a dangerous thing" and "the uninformed are the easy prey of the forger" are non-the-less true. Not all forgers are smart and not all forgeries are clever and well executed. Sometimes just small juicy details are enough to trap the unwary.
