Syrian roundels for 1949-58 & 1961-63 - these actually appear to have still been in use on some aircraft as late as the 6 Day War, in spite of officially being superceded 4 years previously. (It's worth noting that there were several variations on the placement of the stars; I've gone with equidistant but they were unevenly spaced on occasion too.)
These decals are scaled to represent 30", 36" and 48" roundels in 1/300 scale. (They're also ideal for large aircraft in 1/600; equivalent to 60", 72" and 96" diameter.) The actual diameters are 2.5mm, 3mm and 4mm.
