While I have written gas pump books, my hobby has always been restoring air meters, especially ECOs. I have probably owned 20 Islanders, and I doubt I had base covers for five of them.
Many guys have tried to reproduce them over the years, but the cost far exceeds what most people are willing to pay for them. One person tried to repro them in fiberglass, but that didn't work. When the Islanders were taken down, this was the first pieces thrown away. I wish you luck in finding any, and I wish I had a box filled with them.
