I did a search and found a couple of threads on the Tonika and Aelita guitars. I bought this Aelita a few years ago. It was a mess when I got it. Completely un-playable. Horrible frets, very soft brass-like material. Non original bridge. Original 5 pin jack socket. Unfortunately I didn't take any "before" pictures, so you have to take my word for it. The finger board was black with grime, and the frets and board were so uneven it was like a cross of the grand canyon and the rocky mountains. So I fixed it up a bit... The goal was not to restore it, but to make it playable. All original electronics. Dated 1982.
