This is a Project Piece, Covered with marks and scratches, from I assume being mixed in a toy box with other toys.
I tried to wipe a small area with the water but it did not work, since I have no knowledge of the cleaning process I have decided to post it AS IS
Rare Breyer Traditional Model Horse THE LONE RANGER'S SILVER #574 Matte White Rearing
Nothing broken or chipped that I can see, needs a good cleaning and a new paint
Willing to send more photos per request
