Hi guys, I am trying to identify this type of military/army mount I've seen in the past. It was a bent stem pipe that looked like a regular military mount, but collar on the shank ran throughout the inside of the mortise and formed a long nipple that connected the bore into the tenon when assembled. It might be a stinger except mounted to the collar within the mortise? Not sure...but I been going crazy searching and trying to identify this. I seen a couple pipes a while ago randomly on ebay when they had pictures of the stem removed. The good thing is I am fairly new to pipes and I have been soaking up tons of information during this search. Hopefully you guys know what I'm talking about and I'm not some rambling newb lol.
