Kel Lite 2 D Flashlight for parts or repair restoration

Up for auction is a KEL LITE 2 D Cell flashlight. It is in need of a total restoration or it can be salvaged and used as a parts source. It has significant battery leakage issues. When I got it it had one battery frozen inside. There is quite a bit of corrosion inside but the threads are still serviceable. Some of the threads will need cleaning. I can get the lamp side on and off but the rear cap only seems to go on about 80%. Reflector has some silvering loss. Switch has all the parts but will need cleaning and setting up. One screw is not stock. A real beater but still workable with some TLC. Nice project if you have a Dremmel and some time.Thanks for looking.
