1970's Aria Diamond Electric Hollowbody - Made in Japan - Univox Coily

Here is a vintage thinline electric guitar from the 1970's. The logo is missing from the head, but I think it would have originally been labeled Aria Diamond (unless this was the very similar Univox Coily model?). In either case it's a typical Japanese hollowbody from that era. It's fully hollow with two single coil pickups. It's been played and shows normal wear and tear from use. Both of the pickups has some missing plastic, the tuners have been changed to Schallers, and the nut appears to be a replacement. There are two small screw holes in the top where it looks like the bridge was screwed down at some point. The knobs have been changed and the pickguard is missing. I'm including plenty of photos, both flash and non-flash, to help show the true color and condition. The neck is straight and the frets have plenty of life left in them. It plays well and the pickups and controls work as they should. The guitar comes with a nice rigid zip up case as seen in the photos.
