The major difference between SB-28 and SP-3 is that SB-28 featured a modified lower fuselage with rectangular "landing gear doors" and a nose wheel that could be single or double. Sometimes the lettering under the wings is italicized, sometimes it is not.
I have two Iberia A300s that I thought were duplicates. I noticed the mint boxed example has pale grey wings. Immediately, I found my loose example, which has silver wings, and I compared the two.


The toy model made in Macau is the boxed example dated 1987. It has light grey wings and stabilizers, bright orange-red tampo printed upper cheat line, twin nose wheels, information cast underneath the port wing in non-italicized lettering. The variant made in China has silver wings and stabilizers, dark red tampo printed upper cheat line, single nose wheel, information cast underneath the port wing in italicized lettering, and 61123 beneath fuselage.
