Denys Fisher is a well-known toy company in the UK. Eventually bought by Palitoy and then by Hasbro, you can’t find a better Dr. Who series of the time! They were connected to the old Mego corporation, but are not marked that way in any sense and hence are “Mego Like” in this forum! They all came boxed, are quite pricey, but if you are a fan, you need these! These action figures were produced based off the running TV show which continues to this day! The figures are on the 9″ Mego type 2 body type. (same as Mego’s Flash Gordon series). Here’s a pretty cool history you can check out:
