Offhand, I don't know. Are there any markings anywhere on the device? It looks like there's some markings on the glass but it's hard to tell from the photo. What does the "inside" look like - does it take batteries (barrel resembles a flashlight to me)? Is the "bulb" easily removed from the device to photograph it by itself? Please describe it further including any mechanical functions as this might help someone else identify it here.
