Hi Jmrcowboy. I see that's your first and second posts at TreasureNet. So I'll say, welcome to T-Net's "What Is It? forum, the best place on the internet to get unknown objects CORRECTLY identified.
Here is absolute proof of the (brass) tent-rope adjuster ID given to you by Tony in SC. One of the attachments below shows the original 1880 US Patent diagram for inventor H.B. Thompson's tent-rope adjuster, which he calls a "tent-slip." Another attachment shows an example of your brass tent-rope adjuster which was marked with Thompson's US Patent date, Nov. 30, 1880. The other attached scan shows the original US Army Quartermaster's 1889 order which officially adopted Thompson's tent-slip for service in the army.
Those documents are also absolute proof that it is NOT from the civil war, despite what many Ebay sellers have claimed.
You now see what I mean when I said the What Is It? forum is "the best place on the internet to get unknown objects CORRECTLY identified." I hope you'll read this forum regularly... you can learn a vast amount of ACCURATE relic-ID info here, for free. I did.
Great info. Yeah it was found on A WW1 firing range. We have 100 acres. I was researching homesteads. Couldn’t believe there weren’t any on my property. So I went to researching other things I’d heard about in the area. When all the research for the range started pointing to the backside of our property we were amazed. It’s a completely virgin site. Detector goes off non stop.
I live near an old Army base that closed after WW2 and have found more of those than I can remember out where they were camped and doing maneuvers pre WW1.
