In my ever quest to save cold war aircraft parts I recently found(and bought) a nose cone for sale in my local area. The seller hadn't a clue to what it was but a quick eye told me it was from a Lockheed Neptune wing tip tank. Covers the high powered search light:

To add to my luck my friend Eric from Project warbird happened to have the search light that goes with the dome, to which he sold to me. Nice to complete the set up! What's the chances?
