I bought some items on eBay several years ago from a guy that I believe lived in Marble Falls Texas. I remember seening a M-60 Xenon searchlight assembly sitting on a pallet. Don't know if he still has them, I tried looking them up in past history, but it didn't work. Might try googling it by that city.
