WTB Nitecore D10, cheap non-working / broken donor preferred

Non-working would be great to avoid breaking the bank since all I actually need is the larger o-ring version piston.

So I committed the cardinal sin. I left an Energizer industrial AA in my D10 and then misplaced it for a while. It leaked. A lot. So much that nickel plating of the piston is gone and the bare aluminum is also corroded. The PCB and pill are stained and look horrible, but still work. Continuity of the spring is marginal, so it won’t operate reliably once fully assembled. I am still thinking about machining it down and re-plating but that is a huge expense and might not actually work out. I don’t have a machine shop. This is my very first real light that started me down this path so it’s very sentimental. I have an early version, so the piston had the larger o-ring at the tube OD, not the “button” OD.

Alkaline is now banned in my house. IKEA Ladda all the way now! Screw you, Energizer!
