Thirty years?! Boy, do I feel backwards.
Ahem. A little surprised ( though it occurs to me that 'Development' may imply a more modern

Shown here, the lone AC IV with the 17 pounder, I think. The wikipedia entry provided a
minor factoid - a handful of Sentinels were dressed up as German tanks for a movie called
Rats of Tobruk wikipedia article SonofaDingo! The whole movie is available on Youtube!
