I am a brand new member of HomemadeTools.Net! Happy to be here. As such, I need YOUR help.
Dad recently passed. As an avid tool collector he had a basement full of interesting tools of past and present. Mounted on his wall was this little item. It is surely not very impressive in that it's sole purpose appears to be a reminder of a 2 digit code. It is basically like writing 2 digits on a
scrap of paper and pinning it on the wall. The black centers have a pointer which can be set and changed as desired. I'm completely at a loss to figure out what it is. Any help is appreciated!
