Is there any point today in the further documentation of the
occasional obscure, rare or unknown player piano action for historical
or mechanical reference?

Recently I buckled and ventured out to see once of the countless
"please take away" players I get offered several times month or they go
to the land fill, a trend that has been growing by leaps and bounds the
past several years.  I gave up trying to save them in just as many years
ago since speculative sales in my area for properly repaired, rebuilt
or restored instruments (that require appropriate pricing to match)
have dropped to almost nil.

All this to ask if it was worth it for me to salvage the upper and
lower player action out of this early Estey upright player, an extremely
tired piano left behind in apartment.  Said action is one I have never
seen or have read about so I scrambled to get it out but had remorse on
the ride home after it struck me that I'll never use the parts.

Would anybody really be interested in knowing about since it's so
obscure?  Should I save this action for twenty or thirty years like the
many other actions I've been storing already for 30-plus years in hope
of use, only for it to end up as fire tender in the end?  Any thoughts?
