There's lots of stories about Lyle guitars but not being sure what is the truth, I'll just provide links: link1, link2, link3. Supposedly, Lyles were built by Matsumoku who, reportedly, also built Yamahas, Epiphones, Arias and so on. It feels and sounds very... Japanese - well-built, straightforward with a fairly well-balanced sound. It's got a smaller scale (648) than the Yamahas or some other Japanese-built guitars of the era making it a little easier to play. Its body is also slightly smaller, resulting in a relatively light 1530g, and almost identical in size to some early Hauser models. The materials mentioned above are guesses.

Overall, a bit better than average. The guitar has what looks like an impact indentation, about 2cm square, on the lower area of the top (does not show in photos). The impact dented but did not puncture the top. Along with that impact, there were a couple cracked ribs that have been fixed and appear to be stable. There's some relatively heavy belt-buckle-like scratching on the back along with some scuffs and scrapes on the sides and a divot (shows in photo) in the top near the sound hole - it didn't penetrate the top but did take off the finish. There's a also some other minor dings in the top. Some of the tuners are occasionally stiff but still turn fairly smoothly. The neck appears straight and well attached. The head has a typical ding. The frets and fretboard are in pretty good shape. The finish, excluding the dings and scratches, is still shiny and smooth.
