Great topic. I have to agree with the slant grip camp. Especially a later Senior (.177) and a Premier B series (.177) are my fav shooters. Plenty powerful (for closer range target shooting), easy to cock, comfy trigger (in these ones) and grip fit in the hand. This is the vintage milled steel era pistols league.

In terms of the aesthetics it is a very difficult contest. All of the pistols presented do have particular charms and elements of beauty/grand design. No clear winner here. Couple of contenders for the trophy: Haenel 28(R), prewar Senior (straight grip and slant grip), Tell 3. Its all very close.
