These are some of the shad(ow)y railway characters that turned up in Lockdown April 2020.
I think they look quite striking in dark painted undercoat, like mysterious silhouettes or Cluedo game pieces from the 1920s and 1930s.
They were bought as civilians and NPCs (Non-Player Characters) for my Scouting Wide Games and snowball fight projects to go alongside my LBB30 STS Shiny Toy Soldiers 42mm range Boy Scout figures.
These plastic figures needed a bit of height to be adults alongside my strapping Boy Scouts, so I mounted the adults on 1p MDF and penny pieces.
A bit of research suggests that they are hard to find ex-Lionel Railway stock (USA). Now out of production and widely sold out (including from my original supplier below), they were sold or marked as O figures.
