It can be used without any problems. The neck is also fine. Tuning is also okay. Since it's old, there are weather checks (thin cracks on the surface of the paint), paint chips on the body top, paint peeling on the back of the neck, and fret wear, but there are no problems in practical use. It's probably from the late 60s. It has a bright-colored body and neck, which is not often seen in classical guitars. It's very lightweight, so it might be made of some rarely used wood, but I don't know the details. The brand "Maruha (丸羽)" was an old Japanese guitar brand that existed in Japan before and after the war, mainly manufacturing acoustic guitars and classical guitars in the 1960s after the war. It is said that they made things other than guitars during the war (World War II). During World War II, many Japanese musical instrument manufacturers were converted into military factories. For example: • Yamaha → Woodworking such as airplane propellers • Suzuki Musical Instrument → Manufacturing of military supplies and daily necessities • Kawai Musical Instruments → Training radio equipment, etc. Maruha may have been involved in military production as well. They may have applied woodworking and metalworking techniques to manufacture weapons parts, training equipment, wooden boxes, furniture, propeller parts, etc., but there are very few records because it was a minor brand. How about it as part of your collection? It will be shipped in a hard case as packing material, so you can rest assured.
