A RHO Instruments Malcolm style telescope. The protective end caps are fitted. This scope is unmarked but the mounts and scope match other RHO instruments scopes we have encountered. The brass is bright. Optics are clear. The 3/4" tube is 33-3/4" long. The reticle has two horizontal cross hairs for extended range shooting. A well finished set of bases are included. The dovetails are larger than 7/16" for use with Sharps rifles. The rear base has a dovetail base with two screws that mount the rear base. The base mounts to the telescope. The front base mounts in a dovetail. The front base has a spring loaded ball detent to apply pressure to the tube. You must carefully press the ball dent down to insert the tube. The front sight has a small amount of windage adjustment. The front sight also includes the globe sight and inserts which was a option from RHO Instruments. Unscrew the front sight windage screws and lift the ring base out to insert the glove. Includes seven total inserts. The dovetails appear to have been fitted to a rifle previously. We have only this one used example.
