Now that we can see the photos I will continue
These came from Toys in the Attic, they are 7" action figures from the TV show "Fear the Walking Dead" they are not popular, so were reduced, last time I looked the female figure was still available for a fiver.
As purchased they were very grim looking, so have been repainted to make them a bit more jolly (female is based on Patsy Stone from AbFab) It is very easy to reshape PVC figures, you just immerse them in hot water, bend to the new shape and set by applying cold water (these two were adjusted several times, even after painting) at 7" these figures were a bit small for my 1/8 scale Chris Craft so I extended them a bit with Milliput.
7" figures might be a bit large for 1/12 scale (these two would work out at 7' tall for the male and 6' for Patsy) but, depending on the model, might work OK
Another poster on Mayhem was using Dr Who figures which, I believe, are 5", so a little small for 1/12
Hope this helps
