Mystery Barrel: 16" AC threaded, straight rifle, spiral ported w/ rain cover

[Cale]

Title says it all. Looking to ID and price this barrel. Known facts:

• 16"
• Autococker Threaded
• Straight rifled
• Spiral porting
• Threaded removable muzzle
• Comes with homemade rain cover. PVC material covered in camo elastic wrap. Definitely not stuffed full of Brillo pads to reduce sounds signature.

Shot on an Empire Defender and Emek, worked very well with both. Cover is just a little too long to work with a pump gun.

Any thoughts on brand or asking price?

Thanks all!

If it were me id prob list it for 70 and see what happens. Disclaimer Im not very knowledgeable on random old barrels, but since its likely .690 and therefore way oversized for today's paint paired with the incompatibility with pumps I doubt its worth over 100

The barrel is trinity... But generally has a bird cage muzzle break.
