Baby Flattop? No, not really. Although, it somewhat resembles a CD 286. But Instead, it is a CD 24. I'm not at all familiar with battery rest insulators and looking to ICON for some help. This particular example does not show any hints or signs of being a "waffle top" type which is specifically called out in the Price Guide. Could this possibly be "smooth top" variant? I have NO idea. What is your opinion? Manufactured for U.S.Light & Heating Co. By whom? Light Aqua in color. It arrived here in Washington from New Jersey.
