BSA Gold Star DBD 34 1955

BSA GOLD STAR 1955 BDB34.
I am unfortunately having to sell my late father's Goldie, it is in immaculate condition as you can tell by the photo's, my dad bought this bike after my mum passed away, but not to ride but to look at and to reminisce of days gone by, it was running when he bought it in 2016, but took the fuel out of the tank, because he wanted to keep it in he's house.
The bike did come from the Isle of Man and was restored and registered in 2014 and given a age related plate. It has a racing gearbox and everything is as it should be, but it will just want a small amount of recommissioning to ride again.
I am not a bike guy, so any questions I will try and answer correctly.
