Found RC Sub-PART: 2

[Kim Sleep]

I have a friend in Surry, UK. She found this sub,One other Sub and several Battleships.
This is the second sub that she wishes to sell.
Any ideas as to its Name/Classification?
If you are interested in this, I will get you in contact with her directly.
Let me know.
Thanks

It's a Resolution class. Might be an early R&R boat, but it's been messed about with if it is, as they originally came with a pair of piston tanks fitted at each end of the watertight box enclosure.
