Trouble, I did the same thing for the gunner's turret. I took one off a derelict TBD for the same SBD kit I have had as a perennial WIP for years now. Yours is coming along well.
I have an experiment in mind, to make the ring. I picked up the enhanced Kingfisher kit, which includes the ring on its photo-etch fret. I think I can make a template from that, that can be used to punch out the holes in a piece of thin styrene sheet with my punch and die set. Or failing that, to use the photo-etch to make a plastic master, then cast it in resin. I don't have a derelict TBD kit, they're all going to get built
