Vintage Case International Harvester IHC Box end Socket Wrench P1502.  See photos for condition.  Both wrenches shown are included.  

The red wrench has markings that I believe are IH and P1502.  Both sockets are 7/8.

The T-shaped wrench has a Z or N and 27 on largest end, and a logo I can't make out.   The socket sizes are 1/2, 11/16, 3/8".
