It's a bit hard to date some old tools. I have a saw that if you were to go by the patina, it makes one think it is quite old but I can't be sure. One of several things in my shop that I don't know the true age of. I don't have a story to go with the saw. Can't even remember where I got it.
I do have this Stanley No 3, type2/3 Pre-lateral plane that I found in a nearby antique store. As I understand it, it should be from right around 1869 to 1873. The knob on it is my doing. I don't remember if the tote is original or not. When I first saw this plane in the antique shop, I picked it up, looked at it and put it back on the shelf because I didn't recognize it. It was in very rough looking condition and I just did not know what it was. After walking around the shop and coming back to this plane a third time that day, because it was nagging me, I finally realized what it was so I ended up bringing it home.
