I still have a pair of 1920’s carbide gas lamps in the cellar. Nickel plated, no chrome!
Next would be a paraffin lamp, probably from the 1940’s, tin layer completely gone; but not rusted through. Thinking about an XM-L lighting up a mirrored cone; powered by 2x 18650 in parallel, with a rheostat)
Then comes a German Army torch, dated 1964 (2D box-type lamp - soon to be modded)
and then, an 1980s era FULTON US-Army torch (would love to mod it to 4x XR-E-R2, with CARCLO TIR lenses and 8xAA NiMH)
Lot of interesting old lights out there! Mine’s a Maglite 6D, bought as a youth around 97-98. It now has a LED bulb, delivers maybe 100 lumens for 165 h.
I was issued one of those right angle, olive drab lights, complete with a red lens when I was in the Air Force in the early 80s. They also gave us Vietnam era C-rations (second gen MRIs but not the MREs) when we were in the field.
