Hello! I stumbled upon this thted when I was trying to find examples of old Stanley levels that had pennies inserted in them. Found out it was kind of a novelty and then I found this site and thought I might try to find out how old the level was. The first post I read was someone giving all this beautiful detail about someone's Stanley level and it actually made me tear up. I just love people that appreciate old things. The penny inserted in this one is dated 1961, the year I was born and it had been at our family cabin for 75 years since my grandfather and my father built it. My hunch is the level came from my grandfather who was in Illinois farmer who built houses in the winter and he played a big role the construction and planning of our primitive Colorado cabin. I am an ardent collector old things and I have a lot of old tools, some of which I've had to find out what they were. Some are farming tools and kitchen tools so they might not be relevant on this thread. Anyway, I'm new to this and I will try to post some pictures, I apologize that they're not real good, but if anyone would know anything about this "model 0" level I would love to have an idea how old it is. It does not have a patent number on it anywhere which could indicate it's old or newer. Thanks again for allowing a newbie to post here and hopefully I'll get to know the website better and be a little more concise in what I write. I really appreciate what good shape this level is in as my father took such good care of his tools. He served in world War II and I remember early gardening experiences with him, how he taught me to clean the shovels really well with the hose before putting them away and he taught me to use hand drills and all kinds of fun things in the '60s. Thanks again, Ruth
