Starrett 439 Builders Square Casting
*For the collectors!* This is the unfinished foundry casting for a Starrett No. 439 Builders Square, one of the most complicated and expensive combination style squares they made. It looks like it may have been a reject from their finishing machine shop. There is a milling error in the slot for the blade where it looks like the cutting tool wandered, shown in pictures. The pockets for the level vials were never milled out and remain solid cast iron. I found this in an antique store in western Massachusetts and I can only assume it was taken home and saved from the trash bin by some long ago starrett employee. Let me know if you have any questions!
