Firstly, apologies for writing in English, (my home country).
I recently bought a neglected Musima Resonata (I believe the label has the number "730" attached to it) from a charity shop for £15. There was some separation at the base of the neck and at the juntion of neck & body, which I have glued with Titebond. I have been careful to keep all original parts while attempting to bring the guitar back to playability, which it currently is. I have also made a bone saddle from a blank, as a previous owner had installed a basic plastic one which was indented by the strings (the blanks I had were not the full width of the bridge, unfortunately, but should do for now). The fretboard was extremely dry, with oxidized frets that were loose and came out from the slots. I have cleaned and very carefully glued these back, which has hopefully corrected both their looks and improved the action somewhat. They sound "solid" now, when I gently tap them - as opposed to a "hollow" sound, before. The fretboard is now oiled with a fretboard oil.
Unfortunately, one screw was mssing from a cog in the machine head tuner. I have found a modern screw with an exact thread, but this needed a small washer as the screw head was much smaller than the original. I am currently on the look-out for an (original) screw that can replace the current one. If anyone knows where I might find one or is able to tell me what the identification name/number of the screw is, - I would be very grateful.
I am thrilled to play this piece of history, and when both myself and anyone else has hears it played - say that the guitar sounds beautiful ...the guitar tone, ....not necessarily my playing

I would like to know when the guitar was made, if possible. Was it around the 1970's?
Also, could anyone kindly tell me from what woods is it constructed. My belief from what little information I have found so far, is that it has Flame Maple laminate back and sides, and possibly a top of Spruce?.
Whatever it is made of, it sounds truly beautiful. As someone described, it certainly has bell-like trebbles and meaty basses. A very full sound indeed.
I have taken photos that might help, as I have worked carefully on this lovely guitar. Hopefully I am not breaking any forum rules by posting a link to the album?
