I posted an ABUS lock a few days ago, but it was on a red door and had a more modern squarish form. ABUS is not a brand available in the U.S. but their web site boasts (in all-caps English) "MAKING LIFE MORE SECURE SINCE 1924." This lock is rusty enough to be from a much earlier area.
Welcome to all. I began blogging Retained-Images in 2004 at My-Expressions.com. It is gone now.
