The first is a very small Yale & Towne, then a slightly larger one.
Next is a Chicago Lock Company blank. Would this type blank be used for vending machines?
And last is Corbin Cabinet Lock Company blanks. Are these for safety deposit boxes?
Many thanks!
The first two are for early (ca. 1930) Yale cast bronze lever tumbler padlocks which were made in 9 widths from ¾″ - 3″ and used six different sizes of key blanks of that same type depending upon the lock.
The third is a Chicago K-4-L used on their eleven tumbler double bitted wafer locks. The L designates “off center left”, also made K-4 “center groove” and K-4-R “off center right”. Have a multiplicity of uses for cam, switch and vending locks. No way to determine age, they are extant to this day.
The last are flat steel key blanks, made in numerous sizes, those are most likely for steel locker locks and not safe deposit boxes. Corbin Cabinet Lock discontinued flat steel lever tumbler locks thirty or more years ago.
