Hello...I found a belt buckle that reads "Spratling Co Made in Mexico that is inside a round circle. In an oval it reads "Spratling Silver." I have included 3 pictures of this item and I would appreciate your help on this. Can you tell me if these are true marks? I have really did my best to research William Spratling but as I sit here tonight, I am unable to know if it is really a Spratling piece. Thank you for your time and help.
