Okay so it's only a small conversion 15mm small but a head swap, I have some Rebel Minis police figures and I want to have some State Troopers, so using some WW I Dough Boy heads wearing campaign hats from Peter Pig I was able to make a nice set of figures,
here is a comparison of the Rebel Mini figure on the left and My head swap version on the right.

Here is the set all finished and painted as Minnesota State Troopers.

Thanks for looking
