Possibly not - there are loopholes which allow an authentic replica of a known good type to be built and receive a PtF. It all rather depends upon what it is - if, say, you wanted to build a replica Minimax, well the type has such a good record it'd be mostly a case of proving that you'd authentically copied the original design. If you wanted to build a replica Sopwith Camel, well it's got no track record as a civil aircraft, so you'd be treating it as a new type. At the other end of the scale would be something like a Huntair Pathfinder or Midland Ultralights Sirocco, which are specifically banned from flying in the UK, so any "replica" would have to be a substantial redesign.
