I own an orange plastic Unica-Nitor, which came on an older bike from England. The bike frame is from 1954, but most components were early to mid 60's. There's a bit of something that looks like brown leather adhering to the inside of the saddle. Is it likely that originally it was covered in leather? It's still comfy, but I replaced it later with a woman's Selle Italia Anatomic.
