Yep, I bet any underground explorer above a certain age probably still has, or used to have, an Oldham Caplamp. Or possibly one of the Speleotechnics FX series.
In the old days they were also used on the railway for boiler/firebox cleaning. They had stainless steel housings. They were the same shape but were alkaline batteries. I read miners lamps were changed from alkaline to lead acid. Why ? as lead acid is heavier and an alkaline battery was practically indestructible. How do you tell the difference as they need different chargers ?
Got a similar one I just found in my garage, says type 2 1973 on the little brass plate , if I charge it at 4volt would there be a chance it still work lol ?
I still have one of these from my mining days in Australia. Definitely an Oldham. The lamp
Room had hundreds of them.
I've seen this type used here a lot. Thanks, Miles, remain calm and CHEERS!
Found one in my garage the other day, used one underground for many years 👍
