Assuming the Q has the standard "bug" cutout, black handle, is SE, and second generation (flat sides on the trusswork handle and small crosspin above the lockbar/spring), figure $60 - $75. Any variation from that is worth more, from a little to a lot depending on exactly what it ls. Figure $30 or so for the Native, older CE versions are not really in demand. No clue on the Viele, don't collect them or follow prices.
