I've got a Brindles Sentinel Rear Sight that I want to sell, but I don't have any idea as to it's value (or usefulness to anyone else), hence my posting. It's been lying around for while and needs a bit of a clean up, but otherwise TBMK it's functional and ready for use following this. It appears to locate onto grooves on the side of the action of a Centre Fire Rifle and then held tightly in place by a Knurled Wheel which runs down a locating Stud (neither present with this item and I've assumed that they are kept on the Host Rifle).

Is it saleable, and if so, for how much ? If it helps in deciding value, I can provide images to someome who can host them for me but can't do so myself.

Thanks, Vic Thompson.
