This is a beautiful vintage classical guitar from Aria.  My research indicates that this guitar may have been one of the earliest of its kind and was most likely made in the original Aria workshop in Japan.

As you can see, the bridge has detached from the soundboard, and there's a crack in the neck just above the nut.  I suspect both are the result of using steel strings on a guitar intended for nylon classical strings.  The extra tension no doubt contributed to the untimely demise of this otherwise beautiful guitar.  In addition to the usual signs of wear, there's also a binding coming loose near a scuffed area on the back and a small chip out on the top.

Internal inspection reveals the hand crafting of this vintage intrument.  It also appears to have been repaired at some point in the area where the binding is coming loose.

After removing the hardware various glues are used to repair the crack in the neck, re-attach soundboard tare outs removed from the bridge, repair bindings, and even drop fill the chip out.

The bridge and soundboard are scraped and sanded to remove old glue and prepare the area for re-glueing which is accomplished using this clamping caul made in the shop for the purpose.

After checking the repairs, the hardware is cleaned, lubed, and replaced before the instrument is polished and set up for play.
