mignon,

I think the second revision is it!

But I just had a thought. I think you want to write a poem which is accurate to reality, but if you wanted to keep the connection between grandson and great-grand father, than you could just focus on the guitar. Mostly because without the direct comparison between grandson and great-grand father, the line "the future make new space for well-worn things" is a little bit less emotionally resonant for me.

Experimental/rough-cut edit to illustrate a point:

Amid embroidered napkins, iron frogs
my mother placed inside a crystal vase
still keep the Ikebana flowers straight,
displayed as usual on the mantelpiece.
I’m in my daughter’s house. My grandson plays
my father's old guitar, he sits like him,
and sings like him, he carries on! A treat to see
the future make new space for well-worn things:
the leather couch, a tarnished silver jug,
Peruvian paintings on the walls, an egg!
My ostrich egg! An abstract marble nude,
a copper fish, a fist of fossil mud,
and on the étagère, old photographs
of ageless angel faces with no names.
