I been trying to find a source for a particular mirror that I hope you all have some insight into. These were probably first introduced 25 years ago, but I was able to pick up a couple within the last 5 years. They came with a long stem and a bullet shaped plastic housing. The mirror surface itself was around 3 inches in diameter. We used them on a lot of different applications, by shortening up the stem, bending and re-threading them. I'll get a photo posted in my garage today. Thanks for the help.
