There used to be a Russian sub moored at Folkestone but I think has since been broken up.
For unusual how about a T34 in the Old Kent Road?

Every so often it gets repainted by the locals. It was once pink and photographed adorned with scantily clad young ladies. Then it was painted like a large cigarette.

Such a shame 🙁 This is how I remember it http://www.flickr.com/photos/ianoak/86430632/

Its not my picture by the way but I there are a few similar pics in my parents albums some where 🙂

This tank is on my lottery winning shopping list.

Sorry for thread drift.
