Here is an interesting combination lock. Look no marking on the dial!
"Antique click style combination padlock made by GOUGLER" - This is an antique CLICK style padlock lock with the intact combination tag. This is a unique concept lock that works by turning the clicker all the way to the left then count the clicks( eg. right 8 clicks then left 2 clicks then right 8 clicks). Very cool and interesting lock. This lock was designed to be opened in the dark or daylight. On the back it is stamped " Gougler keyless locks Pat.Pend Kent Ohio" Very solid and well made lock. A great vintage example of good old American manufacturing and design of the past. - eBay
I have seen one or two others of this type so it seems to be pretty rare.
This lock sold for $71 (Plus $9 shipping).
