Thanks JD, that makes perfect sense and fits with what I saw. On the single fly damper that the piano does have, at the last of the trichords (at the break), the configuration of the wire is different from these bass ones. I felt that it wasn't a case of fly dampers having ever been removed, as there was no remnant of anything, or evidence of work having been done on the piano apart from tuning. I guess the coiled ends would add mass, and be part of the equation for the "phase cancellation" frequency effect. Counter-wires it is, then!
