ACW, indeed the Coningsby Wing received brand new Skybolt aircraft. Scampton had the earlier free fall Mk 2 which were then rebuilt as BS with their bomb door sets put in storage. I forgot the BS was a retrofit itself so post-BS was a 'simple' demodding.
If you can find an ex-BS I think you will find the new BS nose fairing. The other difference is the Red Shrimp mounting plate on the port side as well as the starboard.
