This one's definitely niche, but...

"We have 40 new heads sculpted wearing British & French style Napoleonic Shakos, Bicornes and Tricorne. These have been sculpted on to a wide range of animal heads including cats, dogs, foxes, otters, rabbits, rats and many more. The idea is to use these to convert some Napoleonic or Pirate miniatures to paint, collect and play some fun skirmish style games. I’m planning to use my converted figures to play Blood & Plunder, Sharp Practise, Combat Patrol, Pulp Alley and Drums & Shakos amongst many other possible games. As well as being a fun, tongue in cheek diversion, these quirky converted ‘critters’ are a great way to introduce some young relatives into miniatures gaming!
Conversion packs are cast in metal. Each pack contains 12 heads and 12 tails."
Pick whichever heads you want. I've backed Sally 4th in the past with no problems.
