Interesting find today

[aWaredetector]

Still in my local park and another interesting find today. Just the brass from a shotgun shell. At 12o'clock it says NO. 16 & at 6 o'clock it says CLIMAX. There is also an U on the left & a S on the right. Still need to research an age .

Until someone pipes in - I searched Google and found Single Shell US Climax No.16 7/8-6C...
