So here is my Mosrite celebrity

As you can see it is more a puzzle than a guitar.
For now i checked many things but i have some questions :
It seems that the upper side of the body is not glued to the internal block in the bridge zone, i can put a shim of paper between them. Is it normal ?
I would also like to play it a little before refin it, to check if everything works as it should
My main problem for now is that some screws are missing. Unfortunately these are US wood screws, and i can't find them in Paris.
Do you know some US supplier that have precise description of these and selling them in little packs ? I don't need a lot of ones, and i am not yet very confident with screw indentification
Thank you very much,
Yves
