Based on the info on ScaleCreep's DeepFriedHappyMice resource webpage, it looked like the middle picture was of TTG figs, but I couldn't find any current Russian web images to confirm, so I didnt post.
I THINK the bottom group are old Jacobite 15mm figures. Simtac, before it morphed into MSG, had the Jacobites in the US. The Jacobites reverted to Stronghold Miniatures in the UK, but the operator there hit a bad patch with family and health problems. (There is an unrelated Stronghold Minuatures currently operating.) The Jacobite/Stronghold is no more, which is a pity as it took several other well regarded lines down with it.
Jacobite 15MM Napoleonics are currently being revivified by Elite Wargames and Models, but they are producing only a little of the old Jacobite Nappys, and no Landwehr.
My personal experience of Jacobites were that they were cast in especially soft metal, which, when combined with their unusually thin legs, too often led to grief. I cannot speak to the alloy being currently used but I have a test order on some fantasy 15s in, so I will be able to advise…
Once the Covid let's them arrive.
