Variety s (state I) was first seen in December 1961, and involved recutting to eight lines over the animal’s ear. Variety sa (state II), first seen in December 1962, fresh recutting involving 11 lines. Variety sb (state III), first seen in October 1963, involved a burnishing off of the old cutting and fresh engraving, is more finely executed; the branch over the animal’s head has been in large part removed. Variety sc (state IV) has been called the “Typhoon” retouch, and was first seen in April 1964. It involves very extensive recutting of the entire top right corner of the stamp. The “Typhoon” retouch is very scarce, since the electro was withdrawn shortly after its execution.
