The Parker-Hale model 5B aperture sight for the Enfield Pattern ’14 rifle. From the Parker-Hale catalogue: “Officially supplied to His Majesty’s Royal Arsenal, Woolwich and approved by The National Rifle Association. Based on the design of our famous models 5A and 6A aperture sight for the Lee Enfield rifles, this model 5B is even better adapted for the pattern ’14 rifle, as it needs no fitting, no extra parts to fit it, and moreover it is far less vulnerable, being largely protected by the original aperture sight fences. All the features that have made the other models so satisfactory are included, viz :– 40 minutes of windage adjustments either side of zero, quick release for the slide, sharp half minute clicking movements and clear, easily read adjustable scales, combined with a strong simple quick release movement for the slide with a spin-up locking device that cannot strain the elevating screw”.
This sight is in lovely condition and full working order. A rare sight.
