Vintage French yellow tray, mid-century

Absolutely gorgeous vintage tray in a stunning yellow. It has a look absolutely industrial. It's a durinox am oxydor. When I saw it in a small shop in the south of france, I couldn't pass it up. I've been thinking about keeping it for a long time, but my house is full of beautiful objects. It's in very good vintage condition, but the handles are a little rusty and the yellow paint is a bit cracked. Look closely at the photos. It weighs almost a kilo and measures 39 cm wide, 24 cm deep, and 4.5 cm high.
