Lol, better question is, who doesn't do this?!
I'm always on the lookout for parts for Maglite restorations and I found an old TM bezel and tail cap. I bid on it and after it was over I asked the seller like I usually do if they had any other lights. She said she actually had the whole light so I paid an extra $5 or so in shipping and got this:
Bent, corroded, not working. I'm an fairly confident this light was about to be thrown away. I completely went through it, removed all of corrosion, straightened it, fixed the threads and voila! It's as good as new on the inside.
I know I've shown this light before but I love it. I have a brand new bulb in it and use it around the house all the time. It's a 1980 ~70,000 serial Paten Pending 2D from Mag's second year in business. An oldy but goody. This old use Mags just have soooo much character.
So to answer the question. Yes, I save quite a few that are destined for the scrap heap.
