Defiance by Stanley Pocket or line level, Pat 12014709, This is a vintage tool with a flat bottom to use without line (pocket level) but could be used a line level. Pat # seems long but thats what it reads. Could be cleaned up to look like a nice looking tool. I was able to read all the writting, a little cleaning would improve it greatly.
