Picked this up today for 50p, very cheap. The strange thing is that you can unscrew one part to just use it on two cells or add the extra tube an use five but you have to change the bulb to do this so dont understand the purpose of this. I have never seen a torch that you can do this with. Artas is East German as i have colour change Military one but never seen a barrel torch by them. I have seen one for sale for £76 but its in grey instead of blue.
