It depends on how you take the bit in, IIRC, TRO 3026 about how each vehicle is a 'type' commonly found though the specifics will differ between Houses. For example we have the Rommel/Axel . . . the Axel is pretty much a clone of Rommels, especially when looking at the fluff (I think) about how they were raided for fusion engines that were replaced with ICE. So while a in the LC its called a Rommel, it might be called Hetaiori in the Free Worlds League with some different looks in the armor and different model of weapons- say a Imperator or Irian AC/20 rather than a DefHes model.
Sort of like how the USSR licensed out the AK-47 design to . . . Czechs, ChiComs, Vietnamese and others that were technically given different names/designations, but upon sight are typically just called AKs.
But I think TPTB have moved away from that for vehicles . . . so the Striker had nearly 25 years to spread across the IS for the Aurigans to get their hands on the plans to build as a staple of their armed forces.
