Thank you for submitting your item for appraisal. This appears to be a late 1970s RCA colortrak TV set encased in a burlwood veneered solid and plywood chassis. Colortrak was a trademarke used on colour tv from the 1970s to the 1990s. RCA was sold to Thomson after 1986. The medium quality TV produced during this era are used for Retro gaming today, which results in a limited demand. The estimate is based on recent auction results for similars. There is no measurement for the sentimental value you might attach to the item.
