Lyman J type shell holders. This is what came with my old Lyman All American press.
Montani Semper Liberi
That was quick, many thanks.
J type used in Tru Line Jr presses also and usually sell if you are so moved.
I'd consider these to be unusual: 14A-45AR, 18S-8mm Lebel, 20-43 Spanish, 41LC-41 Long Colt
YMMV
