Industrial filing cabinet with valves

I sell an industrial furniture with brown flowers, with burgundy highlights. I think it dates from the 20s, 30s, it is roneo brand. Its gilded liserais, handles and milky labeled doors gives it a certain cachet. However, it has some defects, such as rust marks, on the bottom locker in particular (see photos). This piece of furniture is also very sturdy and practical, with a large capacity.
