The 12 string Rickenbacker is a beautiful guitar, but that Kauer Banshee is absolutely gorgeous, you are very lucky and what a win, not an expert on Kauer Banshee Guitars but it must be worth £3,500 and it's gone to a very worthy guitar player, hope it gives you many years of enjoyment.
Refugee is the first Tom Petty song I heard. We had that Hard Promsies album in our home on repeat growing up as my Dad was a big fan. I got into the later stuff, from about Full Moon Fever onward. Wildflowers is still my favourite. I love that album.
