There is a small book by Howard R. Crouch, Historic American Spurs, that shows one pair of CS marked spurs with buttons, also a few excavated civilian spurs with buttons. Do some research and you will find that English spurs have changed little since the 18th century and they may be an option. I don't know of any reproduction for the reenacting market of button type spurs much less a copy of the Confederate version.
Glad you asked that question! It is vital to the core of the hobby!
Fill that rusty canteen with apple cider vinegar, cork it, and leave it in the back of a cool, dark, closet for 16 weeks. That will fix everything.
Glad to be of service!
