I've attached a link...
There are some vintage keys for sale on ebay. Most are LSDA, which I am familiar with.
However there are 3 or 4 that appear to be much older and only say; "S". Has anybody ever heard of or seen this brand? Is "S" a now defunt lock company no longer in business.
I've seen this logo only a few times, so they must be quite rare. Any help is much appreciated, as I would like to know the origins of what I am buying! Thanks in advance!
Best
