Alvarez/Alvarez Yairi, K. Yairi, S. Yairi, and Yairi and Son. There are also a few export models, Wilson and Samick by S. Yairi. NOTE: Due to very limited info available on K. Yairi, S. Yairi, and Yairi and Son models, without photo's I won't be able to do the research necessary to try and find the answers you want. Even then, we are talking about 50+ Years of guitar manufacturing, with hundreds of different models. A lot of which were exported to other countries, where info is even harder to find, so, I can't guarantee that I will be able to pinpoint your EXACT model! I will do my best to gather as much info, and answer your questions. PLEASE, if you have questions in regards to OTHER BRANDS, use the Guitar-General catagory, as I won't be able to help you. http://yairiguitars.spaces.live.com/
