I've been thinking about this topic, and I know that we've had past threads where we discussed the Whitworth 12-pounder breech loading rifle's barrel, breech mechanism, carriage, etc., but come to think of it, I can't recall ever seeing an original breech or dispart sight, nor even a detailed drawing of them. I have saved a couple side elevation drawings of this gun that show the sights at a distance, but you can't make out much detail.
Does the Antique Ordnance Publisher's set on this gun contain drawings of the sights?
