The Vintage Imperial Eastman 123C 6" Ratcheting Refrigeration Wrench is a collectible tool from the United States. Made by Imperial Eastman, this wrench is designed for refrigeration systems, making it a specialized and valuable item for professionals in the plumbing and steam fitting industry. Its unique ratcheting feature adds to its functionality and usability, making it a sought-after piece for collectors and vintage tool enthusiasts alike.

I have given this a fresh cleaning. I did not remove the Ratcheting head set screw. I did spray it down with CLP oil so there's some potential lube to that gear and some protection.
