Chris, Supposedly, before the enlisted visored caps were authorized in 1915, these were worn on the Feldmütze as Unteroffizier Kokarden. I doubt the veracity of that. I have a mint Hessian cap that was issued with a sewn-on national cockade and a split brad Hessian version. I think as the sewn-on ones got pulled off, the split brad ones were just easier to replace (no sewing required). Also, I think that caps that show up in collector's hands without cockades often just get the split brad type as replacements, as they are easier to find and attach. Getting the correct old thread (thickness and no glow cotton) is also no easy task. Chip
