Vintage Furniture Sofa Mid-Century 1950s

This is a single-seater sofa made in the USA in the 1950s. I purchased it at a store called BD Antiques in Meguro, Tokyo. After purchasing it, it was stored in a warehouse for a long time without being used.
The cushions are in no particular problem. The fabric has a zipper so it can be removed and washed.
There are small scratches on the iron parts.
I have cleaned it for this listing, but I believe there may be some remaining dirt.
Thank you for your consideration.
