Sanko Show pans beautiful vintage cookware 5pcs

We have a beautiful vintage five piece set of Sanko Ware show pans. Made in Japan and for my research late '60s and 70s. These are steel enameled pans and the finishes are in very good condition for their age with only minor wear. They do show some discoloration on the inside cooking surface which seems to be pretty normal for what I have seen in my research. I washed them with dish soap and water for the photos but I have not tried to really get in and clean the inside of the pans. The lids are also in Nice condition with only some very minor light scratches that are hardly noticeable. The handles have a nice faux wood grain look to them. Great pieces to display or use. As you can tell they are pretty durable as these are 50 plus years old and still look great. They seem like they were well cared for.
