It is my understanding that PM owns the tooling
He learned the hard way, when Lima went bang and were bought by Hornby he could not get the 201 tooling from them as Hornby reckoned they owned it when the bought Lima and all their assets
Similarly when he did the N Class Jinty and green CIE coaches in conjunction with Bachmann, they brought out the Irish Railway set using his artwork etc
Lesson learned the hard way,
