When I just started collecting polaroid SX-70 I had the impression that there were 2 models, the original SX-70 and after the sonar models. I could be more wrong. After reading and collecting all the model variations I believe that I can sort a kind of a list:
SX-70 (non sonar)
SX-70
SX-70 model 2 (Black)
SX-70 model 2 (Ivory)
SX-70 Alpha or Alpha 1
SX-70 Model 2 Alpha or Alpha 1
SX-70 Special Edition
SX-70 Sears Edition
SX-70 Revue
SX-70 SX-70 Executive
SX-70 Model 3
I will leave the sonar models and Gold plated models for a next post
