Remington Model 4 Takedown, .22 cal. rolling block single shot rifle.  Serial #153000.  Good condition.  22” octagon barrel has poor bore with worn rifling, nice original finish turning brown with crisp markings.  Receiver and trigger guard have fading case colors with light surface rust,  good screws.  Nicely blued hammer and breech block.  Stock and forearm have good original varnish with several light hits and dings.  Original metal butt plate.  Barrel takedown and rolling block action work perfectly.  A very nice example!  C&R OK.
