I'm afraid I have virtually zero information to give you about this French pineapple guitar other than it looks to be a nylon strng instrument (although it originally had a trapeze tailpiece which would imply folk guitar rather than classical guitar) and is supposedly pre-war French (2nd World War, I believe).
Its shape echoes that of the pineapple ukulele. I've not seen a pineapple-shaped guitar before, although we have previously looked at an egg-shaped acoustic guitar.
This guitar does require some attention and as such is being auctioned on eBay UK as a project with a starting price of £50.

Additional: We believe it is a Hawaiian guitar - see the comments below this post.
