Upgraded it with an LED bulb, it seems to have faced a lot of use because the thin bendable lens is pretty scratched. It's probably a construction/heavy work oriented light. The old owner (before it got sent to the thrift shop I bought it from) probably used it for a long time since there were non-corroded batteries inside, expiring in 2028. Great find!
(side note, can anyone identify it?)
