Antique porcelain cross handles. Most likely manufactured by Standard.

Possible scuffs/scratches, discoloration and wear to porcelain and plating. Please note cracks visible on two porcelain sleeves. There is also a crack (w/ missing chip) on HOT button cap. Please examine photos for further details.

This item is from a much larger antique plumbing collection that I will be listing online. Other items available. Questions welcome.
