Antique number 103 brass serial tag. Before modern technology, agricultural cattle tracking was kept by attaching large brass number tags to bovines' ears which could be seen from a distance. The recessed numbers cut by a mechanical stenciling machine.  I have a large variety of antique and vintage collectibles available at my store, Northeast Treasure Finds. Take a moment to browse the categories and many different items I have available there.  
APPROXIMATE SIZE:  3" by 2” (76mm by 51mm). Weight = 2.55 ounces
CONDITION:  Natural age and use wear patina. No signs of damage or excessive wear. Review images for condition accuracy and verification.
WHERE I GOT IT:  This comes from a family member's personal collection. It has never seen the internet, it was collected during the 1970s-1990s via auctions, flea markets, antique shops and dealer shows. This piece has not changed owners in over 40+ years.
★ Everything is sold as-is, preowned authentic vintage/antique. Images are of the actual presented item, read all details and examine the pics thoroughly. If description has erroneous or misinformation, polite input is encouraged.
★Pictures are taken with professional equipment and conditions. Minor irregularities and blemishes can look prominent when otherwise hardly detectable to the naked eye- my pictures don't always reflect the true beauty and condition that a hand held examination will provide. Many of my feedbacks validate this claim.
