My favorite wooden folding chair

I bought this from a neighbor lady who wanted to get rid of it due to all of her girlfriends fighting over it. There are no manufacturing markings on it, that I could find. She had it for 50yrs+ before I bought it and said it was an old cruise ship deck chair. I don't know, but it is a fun conversational piece and comfortable. I have had it for 5 yrs now. Anyone have any idea of it's manufacturer or what timeframe it was built? Is it a reproduction? I'd just like to know, thanks if you could help...
