I know a little bit about them if you want to pm me some pics and makers marks. Certainly not an expert at this but do know a little. If you have any civil war items, I might be able to identify them and give you an approximate value since I have a Civil War memorabilia price guide that's only a year or so old and use it to help me with my button collection but it has other items like bayonettes, swords, etc. in it as well.
