Because there are designs that use different magnet types, wire insulation materials, hand scatter winding, wire gauges and number of windings to give very different characters. I doubt very much that Hofner would bother to vary the basic design of the staple pickup between its Chinese models. It makes more economic sense to benefit from the higher production quantities of combining both the Ignition and HCT staple pickups. Chinese production is all about volume; German is all about master craftmanship; whether German pickups are handwound I don't know but I bet the basic materials and design are the same. These are not technically advanced pickups.
