Have this old Yamaha S70 I'm trying to date. Nippon white lebel (now yellowed) but serial number 531367 which doesn't seem to decode. Any ideas of the year? Pics attached.

Its a japanese classical guitar from the 70's. I would remove the steel strings.
Where's our resident Yammy expert? I believe this model was first made in the late 60's. However, someone who knows something about Yamaha SNs may be able to narrow down when this one was made. I agree though, those strings appear to be steel and have to go. How's the neck look?
