Here’s another of mine.
Although it looks almost-like-new, I have a feeling that this one is quite old, as on the box it says ‘Yale & Towne mfg co’ and on the keys, it says Yale&Towne.
I know that later yale products had ‘Eaton Corporation’ on the keys, so this little puppy must surely be an old one! Never used though, looking like brand-new, with box included!!

This padlock is a small 830 type, so the keys are miniature, and would not be able to be matched-up with a Yale cylinder.
Again, I won this from an auction some years ago.
