Comes complete with Certificate of Authenticity by The Movie Reliquary. In 1967 only 3 of these portcullis spikes were made by Shawcraft Models who made the original monsters and Daleks for the show in the 60's. The spikes were retained by BBC Doctor Who set designer from the 1960's Chris Thompson who we obtained this from many years ago, out of the 3 portcullis spikes only 2 are known to have survived, one which we parted with and is now in the famous Neil Coles Science Fiction Museum and the other which we retained and are now selling here on eBay. 

As it's hard to gauge a price on a screen used prop from this era of the show we are open to offers, with it being Dalek related and from a missing episode brings lots of interest and value to the prop.

Any questions please don't hesitate to ask and will do the best we can to answer any.
