【Rare, Unused】Showa Retro Aluminum Cooker Set with Kettle, Camping

This is a retro Showa-era aluminum cooker (kohel) set that was found while organizing my parents' warehouse.
It is estimated to be about 40 to 50 years old, but the aluminum still retains its luster, and it is presumed to be an unused dead stock item. How about it as a vintage gear that won't be the same as others in the current camping boom, or as a collection of retro Showa-era雑貨 (miscellaneous goods)?

[Features]
• Super Deluxe Full Set: Includes the pot, kettle, stove stand, and the original vibrant orange stacking belt. It is very rare to find such a complete set.
• Lightweight & Compact: Everything fits snugly inside the large pot (stacking) and can be secured with the belt.
• Retro Design: The vibrant light blue knobs on the kettle and lid, and the color scheme of the belt retain the atmosphere of that era.

[Condition]
• Believed to be unused, but there are slight signs of dullness characteristic of aluminum due to long-term storage, and minor scuff marks (please check the photos).
• The metal fittings of the stacking belt have slight rust and discoloration due to age.
• The kettle knob (plastic) is firm and has no cracks.
• Original box is not included.

[Notes]
• This is a very old vintage item. It is not in perfect condition like a modern new product. Please purchase only if you understand the characteristics of retro items and items that have been stored for a long time.
• If you plan to use it for actual cooking, please wash it once before use.
