Industrial drawing desk or architect

Sells adjustable drawing desk and its height-adjustable chair also. The whole is very old, in metal and wood. The desk tray has an inscription. Note that the tray is damaged underneath because we used a lamp that screwed on it. This trace is only visible by looking below the tray. Very nice quality piece. Very practical because can be put in different positions with a lever that then screws to stabilize the whole. Heavy.
