Aha yeah it's a headscratcher, first time I've seen it on a fig.
I might do a bit of digging to see what other bodies have the smaller balljoint in the neck (not sure if a ttm22 does) and see if I can land a bargain somewhere, I know red skull has it, possibly Sweeney todd and I'm hoping the crow does as they can be picked up pretty cheaply at the minute
I've found the body relatively cheaply. PM sent.
