We have a vintage/retro silver tone metal belt buckle from around the 1980's or so.  It is in 2 parts as shown in my photo.  When it is fastened together it measures about 6 7/8" in W x about 1 3/4" in L in the center and about 1 3/8" on the higher points on either side.  It will hold a belt up to 7/8" wide.  It does show some surface wear on the edges especially on the center oval.  I have tried to show this in my last photo especially.  I will ship internationally, please contact me with your country for a shipping quote.
