In 1973 a pair of pistol made for Pedro IV of Portugal, worth 100,000 euros, where stolen from the Military Museum in Lisbon. They have finally been recovered. The Publico reports (translated with google) …
Designed by master gunsmith Arsenal Real in Lisbon Thomás Jozé de Freitas, weapons (one-offs that charge after he unscrew the pipes, which are embedded in gold and silver) were eventually stolen, along with a set of parts lowest, by a burglar who at the time was right pages in the newspapers but that, far from being an Arsene Lupine, it would reveal a “brick” because that stole not meet even the approximate value of the goods. Still, it was celebrated by the method, but effective, he chose to commit the crime: he hid inside the museum, behind a large clock, and when he was alone, plundered what was at hand.
Thanks to my Portuguese source for sending me the photo and links.
