The old Scotts Guard was made by 3M, it was sold by K mart and other discount stores as a house brand. The newer emulsion was developed in the 90s, Ferrania states that has nothing in common with the 3M emulsion, the Ferrania I shot in the 90 and early 2000s was nutural, I liked it as well as other E 6s of the time. If Ferrania new film makes it to market in the US I will try it.
