1969 Recliner Lounge Chairs refinishing

Am seeking advice on recently acquired skip bin gold
- a 1969 four piece lounge suite. refer image
date verified by the "Made in Japan, partly assembled June 1969" stamp on underside of arm.
one original owner
some joints to be dowelled-glued, and recovering to be done.

advice from the experienced folk appreciated on the following;

1. what is the most likely type of wood?
2. what would be best refinishing process and coating?

am considering a light 00 to 0000 sand followed by coating with an appropriate finish consistent with the light wood and existing clear finish.

thanks, cheers,
