I think it was some kind of resin casting though
exactly what kind I have no idea,
it was a off white/grey colour and not brittle so
your guess is as good as mine on that.

Nicely sculpted piece with a good pose.
Real fun doing the paintwork on something like this I kid you not,
mainly for having a go and pulling the
job off to a just about acceptable
standard was rewarding enough in itself,
I did like the finished article however.
