Incredible Handmade Vintage Reversible Raincoat S

I fell in love with this piece and have to find it a good home. Handmade, clearly very old (50s-60s, I’d guess), and double-layered/fully reversible. The navy fabric feels like a waterproofed nylon, while the patterned is probably acetate. Solid side has curved deep blue horn buttons, while patterned side has fabric covered dome buttons. Several flaws: see all pics. Small holes noted, plus side seams are a little rough. It’s very old! But so cool. Measured flat: 19” pit-to-pit 39” length
