Ronéo industrial furniture with valve

I sell a ronéo clamshell piece, I think of the late 20s... It has been stripped on the outside (note there are still a few small marks of paint), and the interior color is the original one. A handy piece of furniture to store documents, or even shoes. The exterior is stripped, in places we can see that the raw metal mixes with a darker color (grey/black), (see photos). A few small defects, due to his old age.
