Just spotted this - auctioned last year in the US. I wasn't aware that any "Wheel in Space" style original heads had survived. It sold for big money. Any 60s cyberman experts care to comment?
LOT 968 DOCTOR WHO SCREEN USED “CYBERMAN” HELMET FROM THE 1968 EPISODE “WHEEL IN SPACE.” PRICE $22,500, PREMIUM $4,500
According to my records, it's the third most expensive item at auction, after the Bamfords movie dalek last year (£38,560) and Dalek Six-ex at Bonhams in 2005 (£36,000)!
