Richard, it was definitely an in service vehicle. It was deployed in Germany as part of BAOR. It had many innovations that have become standard since then, such as the ability of the commander to take control from his position, lay the gun and fire it…
Interesting training clip from 1956
20 Mk 1 were built, then 165 Mk 2.
28 ARV vehicles were made as well.
