I got this 1950's Rayovac torch from the USA on ebay for about $20 after postage, it's all metal & glass construction with a near perfect chrome finish and works like new. (the middle one)
It's the one in the middle shown next to another vintage light and a 2C cell Maglite on the right.
I did some modifications to it to make it approximately 15X brighter (500 lumens) & rechargeable by using 6AA batteries instead of 2 D's and a bulb from an American firefighters lantern. It runs for 1.5hrs per charge and is comparable to my bike's headlight only whiter.
Here's a pic showing the difference in the beam between standard & modified:
It fits easily into the pockets of most pants & shorts - only problem is after about 15 minutes the head gets really hot.
Can't wait for my next bushwalk.
