I noticed this was your very first post - so, Welcome Aboard RedBrat! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forums: Select Your Area.... and selecting location information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country). You might also consider adding your state (or country) to your displayed profile (SETTINGS -> EDIT PROFILE) so if you ask a question, etc. - people may have more success helping you (your location may help, etc.)...
Ok i found one of these with the other parts to it and also have no idea what it was. When i flipped my plug it was surrounded in an even pattern by these little metal discs. not a button. i also couldn't find all the tiny dics. I think it says it was patented in 1870 whatever it was
That's what I was thinking originally, but it doesn't look sharp enough to be a spur rowel. There is also writing in the center circle, but I can't make out what it says.
