Ok sorry for so late and that i put up old post. However i have made a litle reserch regarding this subject. Delivered gladiators was without swastika on top wings and with all the technial signs (1937-1938) at some point betwen in (probably august, before presentation)1938 the airplanes was repainted - white circle apiered on top wings, all the technical signs was overpainted. Also swastika appiered a litle bit bolder then on delivery planes. And yes, from few picteres (mushroom publication) i can conclude that all insignias were simetric. Also on fin tail apiered shield emblema (KAP) Also spiner and wheel disc color diferented from 1st and 2nd squadron. 1st was in polished metal/aluminium, 2nd was in green (same color as airplane). Regardin 121 (im building it) im not sure regarding fin tail color as at the time of crash (photo) it has alredy repainted.
