1876 Cast Iron Sash Lock Catch

If you have a window lock that was patented Jan. 4 and June 13, 1876 and are missing the catch, here you go!  The patent dates are marked on the backs.  One catch is more polished with designs and the other is a plain dark iron with warm patina.  

Sold individually. Please specify Dark Iron or Polished in the comments section at checkout.
