I bought it as a A-700, what I think it is, but unfortunately no more infos from the seller. I regret I have no indication to date it. Sold as end of '70's.
I'd say the headstock inserts are abalone, but not the fingerboard ones.
The neck is very good to my taste and it allows for a very low action (too low for me, as, it makes bends very difficult ; impossible to place my fingers below the strings to push them up). In conclusion, I'd say it's a good guitar, especially with the pu upgrade, that makes it a very pretty blues instrument.
