1971 Teisco Guitars and Checkmate Amp

During the 1960's and 1970's, I saw and played many guitars made by Teisco and many different Checkmate amps. The amplifiers might be numbered anywhere from 8 through 100. Also depending on when they were made, the same numbered amp might look different or the speaker(s) size might vary in different years. Here are the Teisco electric guitars and one Checkmate amp sold by Radio Shack in 1971. We did not have a Radio Shack Store in Mount Airy until the late 1970's. I did see one of these amps either in Winston-Salem or Greensboro.
 If anyone has a better photo of the amp to confirm the correct number, I would appreciate it.
