Your Dagmar reference struck a chord with me so I have to assume I have heard the term before.
Nonetheless I look her up...
She had a heck of a pioneering career for women in television and certainly set the stage for the popularity of large chested women in entertainment, as well as intelligent women playing ding bats (Jean Stapleton from All in the Family also comes to mind).
I found it odd though that she never had children, that was certainly not the norm in that generation.
On your mod:
I think it is a grand idea, and I LOVE it already !!
However I am sort of surprised you did not check out the Army Surplus shop on Division, or call out to Fairchild DRMO yard for some old ordinance dummy rounds/bombs. There are some that would have had the perfect leading cone that you are looking for on this mod.
Your Veteran status should be enough for you to get stuff from the Air Force out there, though I have yet to investigate this myself (soon.....my pretty, soon.....)
Anyways, you got my attention again
