The picture shows a view of both sides of this Large Old Unmarked Metal Padlock with Working Key. If there are any markings we can not see them. The key was found with this lock and it works well. The lock opens and closes easily. The lock and the key are both made of steel. They are not dated but they are old. To judge the sizes the pad lock measures 2-7/16'' x 3-1/2'' x 3/4''. The lock is in working order. The key appears to be in excellent condition and the lock looks to be fair condition with some old rust and old black paint as pictured.
