The replica business has been a thriving industry for decades and I'm not aware of many, if any, companies being stopped from making "copies" of long discontinued models.
Ferrari has issued literally hundreds of lawsuits to protect their IP. I've nothing against replicas, "Total Headturners" is a stand I always visit at motoring events, but some of them are on shaky ground with regards to trade marks.
All of which is contrary to my original point that I'm not convinced Suffolk's demise is very much the result of a legal threat.
