All three of my Componons, except one, were bought new in the late 60s and early 70s, and all had both front and rear black plastic push-on caps (105, 135, 150). Much later I bought a used Durst 210 Componon that came with an apparently original rear push-on cap, but the front cap was a substitute push-on. Each lens is kept ready for use in its proper Omega cone with both caps in place. I believe in taking meticulous care of my equipment, and they are all in like-new condition.
