The oxygen tank is made of aluminium tubing that was once serving as a TV antenna and the acetylene tank a casing for a cigar - (NO...I Do Not Smoke!!!!). The pressure gauges are carved from rubber , so as the vise. ( My poor daughter couldn't find it in her schoolbag next day!)
 

Here you see the close-up views of the vise and the dirty plastic tray containing rusty bolts. The handle of the vise and the bolts are made of pins. The rusty effect was given by first heating the pins on an open fire to a black state , then dry brushing . By the way, the tray is from the packing of a medicine pill. The workbench is from balsa, burned locally with the tip of a soldering iron to give the aged effect.

The walls are from 12 mm thick gypsum boards and it was very easy to etch contours on it to give it a briquette look. The hardest part was to scrape off the cardboard lining to reach the gypsum. The blue painted region on the walls are the un-scraped cardboards which gave an identical look with a plastered and painted wall. It is also a common practice to leave the higher parts of the walls unplastered and natural in those modest shops.
