Thank you very much for your input
Pete, that is a very detailed list for just that one button
Roger, you are right about that first button, it is (IMO) a late 18th early 19th century button. The construction on a few of these buttons show them to be early, and as you know, on the IOW we have mountains of military items in the ground as it has spent most of the last 300 years as a military camp. I've lost count of how many Brown Bess musket balls I have found
