The last I heard from Data, he was planning on offering both the "Vault Cap" and the "Vegas Knob" as optional accessories on the 007. So the old cap should be standard equipment.
No, unfortunately not. Data has said in the past that since each light and cap are cut from the same block of Ti they will have a unique fit that can't be duplicated . He said there's no practical way to machine a stand alone cap that will fit a particular light.Would we be able to upgrade an old Spy 007 to a new tail cap?
