I’ve been working on THIS series for four or five years. I have a photo update below of some additions. Unfortunately, each time I find one, I learn of others. A bottomless pit.
Not sure if it is any different — or you already have it — but the Micro M.I.T. 3001 in 0.5 ticks all the boxes (and it is basically a clone of the rOtring 500); more here.
A few brands have slapped their labels on this style with the mid-body indicator (Berol, Stabilo, Tempo, Fuang, others?) but the Platinum was harder to find than I thought it would be.
