Well, I've played many Nationals over the years and they are supposed to be the real thing but didn't play or sound as nice as my Johnson "monkey junker"...
Guess some folks would call my 60s S.Yari junk... Bought it for $40 at a pawn shop... Soon afterwards discovered that my old 1966 Martin D-18, which everyone said sounded great was being left home in the case when I would have gigs... Ended up giving the Martin to my great niece because she plays beautifully...
Still playing the junker S.Yari... Played it last night in a joint in Concord, NC and had the folks wanting more...
