some "moldy oldies" OLD yale,corbin
the oldest lock here is a cast-iron Yale warded padlock (pictured second.) ,along with two blanks to impression keys,
next is a "101" (pictured first.)i believe this is also a Yale,along with appropriate blank for impressioning a working key.
the newest and last Yale is a five-pin tumbler ,long shackle padlock.(this lock has ball-bearings cupped in the tip of each keypin...
now on to the Corbins...the eldest is the railway-style lever lock,(the most recent addition to my collection.)
and the old brass padlock came directly to keypicking from the bowels of HELL!!!
you figure it out..=)
