There is one Beech 18 in Iceland that is maintained in airworthy condition and occasionally flown. It is 52-10672 / TF – JFA that is based at Akureyri on the north coast of Iceland.

On the link below, you can see it in flight 21. of June 2008. It is the latest photo I can find of it in flight – but I can not be sure if it has flown since.
