Unfortunately I got rid of all my 1:72 Eduard WW1 stuff.

?? 1:144 scale rigging
This is possible, a little unusual, some may even say perverse but..
You need to just scale down and find a friendly Plastic Surgeon that can supply you the facial suture in mono (you can't buy it from the manufacturer), I've tried.
I did have the great privilege many years ago, a 6 x hour job by the way, of seeing a young fellow have all of his R) side facial nerves re-attached under microscope. He got drunk, had a fight and got pushed through a plate glass window.
Yes, suturing nerves together, end to end with a needle that you just cant see. Now that would be rigging for Australia on the Olympic Team!
Anyway, enough of the gory stuff.
It’s possible to rig WW1 in 1:144 scale but I’m quite sure the judges at your local comps won’t even see the rigging.
Cheers
