I picked up this guitar in February 2009 and it has a market value of $80.99. This is a Sears Silvertone Electric Guitar Model 1406 from the late 1960's. The sticker on the back of the headstock was there when I found the guitar. Based on the headstock I believe this is actually a late 1960's model. As far as I can tell, this guitar is all original and complete. This guitar does have some nicks and dings in the finish as well as some crazing that is common in a vintage guitar. The pots are a bit scratchy and the knobs have chips/cracks in them but everything seems to work.
This is a late 60's early 70's Silvertone made by Teisco of Japan. This is a similar to the Mosrite or maybe a bit of Stratocaster. It's a small student/child size guitar. Teisco made guitars for lots of department stores and Sears joined up with them in the late 1960's.
The Teisco brand name stands for 'Tokyo Electric Instrument and Sound Company'. Teisco was founded in 1946 by renowned Hawaiian and Spanish guitarist Atswo Kaneko, and electrical engineer Doryu Matsuda. Teisco guitars sold in the United States were badged "Teisco Del Rey" beginning in 1964. Teisco guitars were also imported in the U.S. under several brand names including Silvertone, Jedson, Kent, Kingston, Kimberly, Tulio, Heit Deluxe and World Teisco. While guitars manufactured by Teisco were ubiquitous in their day, they are now very collectable.
