Actually, the HRWs were hailed as great, then yanked out because they were too "HiFi", or too shrill, too bright, too muddy, or too dull (take your choice... I've seen all those comments) only to be replaced by some SD or Throbak or Mojo, etc. Then those muddy, shrill, dull, HiFi pickups get put on Reverb for $500 a set because they're so great. Same with the Schaller pickups. People would often yank them and put in SD 59s or Seth Lovers. Once Heritage started to put in 59s and Seth Lovers, those crappy pickups were yanked out for somebody else's pickup.
The same thing is happening with the 224 Parsons pickups. People yank them out because it's easy to do, then sell them for big $$$$, extolling the virtues of these great pickups.
And if some random person winds a pickup and puts a Pat Pending sticker on it, it becomes a PAF and is hailed as a wonderful, detailed, vintage sounding pickup with amazing harmonic bloom and sustain for days! It's amazing what a little sticker does for the sound.
.... or at least for a while.
I'm not saying we're all gullible, but yeah, we can be!
