There appear to be different brands that used this same design for their flashlight, just as with the Kingdom of the Crystal Skull flashlight. Is yours an Eveready?
Also, did you polish the metal after you removed the paint to get the shiny look? RaiderLight's has a more distinct matte finish.
By the way, shouldn't this topic be included in the
Indiana Jones "Real World" Props thread? That's where all these type of items that exist in real life and weren't made specifically for the movie are carefully catalogued to keep track of them.
