Antique leather platform rocker

Antique (possibly handmade) leather platform rocker - Belonged to my G-Grandmother and was told that it was her father's chair - Have given it a good scrub with saddle soap yearly to keep the leather soft - Still rocks but isn't in use -

Chair is a heavy wooden frame covered in a dark red/black leather - Small rivets attach leather to frame around unseen edges - decorative rivets down side of arms - Leather seat cushion appears to be separate piece, but won't easily remove, so I haven't tried to force it - Back of rocker is completely covered - Covered arms stop at the "hand rest" area where they continue as carved wood down to the front arm panel

Underneath are 2 large springs - Not sure what chair is stuffed with (makes a crunching sound if depressed) - Looking underneath a few curvy wires can be seen as seat supports through the cloth and burlap - no tags, initials, etchings or other identifying marks can be found.
