If anyone is interested in a Barr & Stroud rangefinder, I have a 500 model that I would like to sell. Ranges in yards. It has crystal clear glass and is in excellent condition. Comes with the military tube case that it goes in. Ranges from 500 to 20,000 yrds. $550. If interested, you can email me direct at email@example.com or you can call at 570-713-5538.
