Better pic showing size/scale, loading the monster along with "Steelton Rich".

Just got this from Steelton Rich, it's a list of scrapped stationary steam engines from the mill/building that these wrenches came from.  Dated 8-22, Still trying to figure out which engine the wrench is for by looking for drawings of piston nuts of each.  Maybe the print/drawing is still there, maybe not.
File should enlarge for you.

Some info on the 3rd largest wrench from the treasure. These gonna be at, http://www.coolspringpowermuseum.org/

interesting weld job on that smaller wrench.   

Thanks, I wish I actually knew more about forge welds but alas i can only explain best what i see.  I believe that particular joint is kinda normal for joining 2 pieces.  In the next video I'll feature a couple wrenches with a different looking weld.  1 I never seen before.

Page & Storms wrench from the mill.
Trying to get info I can on this 1. Can the shape of the opening and that stamped number give a indication of years produced. It's a 3" opening and 24" long. This company was taken over in 1919.

Another video of a different neat wrench. I believe it has a cleft welded head on it.  I'm posting a different wrench with video the next couple nights. Thanks 4 looking.
