1964 Curtis Matis 20'' tv

I am new to this board. I have always been fasinated with old tvs and electroic equipment. A friend gave me an old Curtis Mathis b/w tv. He said he got it in 1964. It is a small console about 20''. The chassis is a vertical type that mounts around the picture tube. The only # I could find was 15A253 on the chassis tag inside. It has the screw on legs so it can be used as a table model. Well it had been in his barn for years,filty as heck. I hooked it up and it seemed to have sound but picture tube would not lite up untill i turned it off and a narrow line with a dot in the center would show up for a second. The flyback may be bad. It has some cracks on it. Would this old TV be worth messing with or best going to the trash heap?
