the best you will get is a head made by cyberman on the rpf, costly but worth it. if he is still doing runs they can be solid fibreglass resin or latex for a puppet. ive a 3 quarter completed accurate puppet with sourced glass eyes, real material etc..they pretty cool its in storage atm cos im unable to display my stuff anymore so don't think I got pics.
dunno wot mine would be worth now or id offer it for sale, I would need to go try dig it out and see if its all still there
