4.5 inch Mrks 3 - 5 "Drill" case

While searching the internet there was a insert from Royal Laboratories Museum with a photo of a 4.5 inch Mrk 3 - 5 Drill, but unfortunately the photo has been removed or I could not open it. Maybe some one else has better luck.

I wonder if some one could help me with this one. It would appear as if this case was cut down. Currently the length is 335 mm. What would the original Drill round have looked like ? Was the marks 3 - 5 seperated ammunition?
