The A string saddle broke!! Fell apart while playing this morning. Seems like a short time to have before breaking but Guild doesn't not warranty them they said so I will buy another set and have extras.
The brass ones are back on for now but there is a bigger, beefier tone with the ebony.
I guess only an original owner could tell us. Otherwise there is no way of knowing what was on their stock. I don't think catalogs would mention it.
I might try making my own with scrap oak. That would be a fun project.
