Default Information about construction and woods

Hi all! I've recently got my hand on a Juan Estruch guitar, model Trovador 100. I posted about in another section and could get some good info there and around the web. As far as I can tell, it's made in Spain around the 70s or 80s.

The first owner bought it for decoration and gave it to his nephew, the guy I bought from. He never really got into playing and looks like the guitar hasn't been played at all!

I'd like to ask your help concerning the construction and the woods used. Nut and saddle are plastic (nut was split, noticed as soon as I removed the strings).

I'd like to ask your thoughts about possible woods used, and the construction of it. I took photos and made a video from the inside and outside of the guitar.

The neck got my attention. The heel is different from what I'm used to see, looks very "sharp", let's say. From the inside, the neck joint is also different from what I usually see. It's sort of round and there's a metal pin or something. What could that be for?

The bridge as got two white stripes, where you tie the strings. I see them all the time in Yamahas. These look like plastic, or would it be bone?

The back of the guitar is slightly separating from the binding. It's just a little bit and there's a millimetrical gap. It closes when it push it but comes back to the same place again. Would that be worth of repairing? How could I do that? Should I really glue it back or just filling the little gap would be fine?

Finally, the label is coming off. I'm guessing white glue will do the job right?

Anyway, I like to heard about what you guys can tell me about the guitar from the pictures and video. Thanks!

Looks like a cedar top. Sides and back...?? Walnut, perhaps, but seems too dark for walnut.

A glue stick works well to re-glue labels. I would NOT use white glue.

Don't see a photo of the "metal pin" in the heel joint, so cannot comment, other than that Spanish guitars are usually built with Spanish heels.

Tie block is as you say - plastic or bone (white inlays).

If there is movement on the back, it should be re-glued, but the glue must penetrate the full wood-to-wood joint.

Thanks! May I ask why not white glue? Glue stick sounds like a better idea anyway, it's just curiosity.

Sorry about the picture or maybe I didn't express quite well. By metal pin I mean this (maybe a staple... I really don't know what that is):

I see. You mean like something it was used for clamping while the glue dried and later was forgotten to be removed?

Probably used it to hang the neck during construction - maybe to hold the 2 pieces of wood together while the glue dried - who knows - probably more work to remove (and too much risk of damage to instrument) than it’s worth -

You can always use it to hang your rattlesnake rattle - ;-)

70's model, family of barcelona builders. cedar top, rosewood b/s. if it's not it too bad of shape, get it up and running. those guys hold some value.

Wow, great links, thank you so much. I had already visited the last one and sent them an email but no answer yet.

Yep, it's not in a bad shape at all! Just some issues with the frets and the back, minor ones. Friends from the agf have advised me well and soon the guitar will be back on its feet.
