I looked through that guyās feedback and it appears he may have only sold two: one in Sep./Oct. 2012 and one in Dec. 2012, each one for $75 (which is the lowest price I recall seeing him ask for a #19).
Hey Adrian,
Thanks for the drainage system patent. I never knew that Master started making locks with such a feature before, and learned something new from this thread! I looked at some of my locks and it seems that other Master padlocks were made with the drainage system too: my circa 1960s Master āSuper Securityā #81 (their first padlock to have a 5 pin cylinder, I believe; any knowledge of what year that one was introduced, BBE? :-), a circa 1980s #15 (of a similar vintage to your #19), and some other standard pin tumbler models from the 1970s to the 1990s have a small hole at the bottom of the receptacle for the shackle toe in the lock bodies (clogged up with dirt in the more heavily weathered ones), which may be a drain hole, while some 1990s #5 padlocks of mine have a huge hole.
Circa 1980s is a good estimate of the age of your lock. The #19 originally had the outline of the old Master plaque logo stamped into the bottom of the lock, framing the key number. This was removed at some point (and your lock doesnāt have it), and eventually the early Master bumper design was replaced with the newer blue bumper design. Same goes for the #15. I donāt know exactly when the bumper design change occurred, but BBE said in another thread that the smaller pin tumbler models (nos. 1, 3, 5, etc.) first got their bumpers in 1987, and those bumpers were apparently the newer blue ones (albeit in a slightly different variation at first, it appears), so the models that already had bumpers of the earlier design may have switched to the newer bumper design around that time.
