Looking at the photo of ZS-OOS I saw in the description that is was a Boeing 747-258C. When I searched the database I for some more pics of the same airframe I found one of the a/c in it's EL-AL time. However the type was then called Boeing 747-258C/SCD. But I could not see any signs it has a Side Cargo Door on the main-deck. The airframe obvious has a nose-door however.
My question is, Did Boeing build 747's with main-deck nose loading door without a main-deck Side Cargo Door? And if so, how many were build for which customers?
