Here is an interesting Scandinavian style padlock. I have not seen one of these before.
This padlock had a high bid of $1,363.56 (Plus $6.95 Shipping). -----This lock has a keyhole cover that is opened by pulling a tab at the bottom of the padlock body. It is marked with the PRUTZMANN name in at least 3 places, including the key. 3 3/4" tall. Steel. Good condition. With the original, PRUTZMANN marked key. - eBay (2 April 2012)
