got a nice original prop off ebay, or rather had it bought for me! The central rod core from the heart of the key to time, COA from Propmasters, part of the rigging that made it rotate in the first episode still attached, very pleased to finally get item from the Tom Baker era
know the feeling Mr Saxon, thank you for parting with it! it is great --must have been tough for u, my partner says I would part with anything but my props! Not including her of course!
