This MD-82 was originally delivered to Finnair as OH-LMP in April 1983. Over the following years it also flew with Austrian (OH-LMP), Nordic Airlink, Aviajet, Nordic Airlink (all as SE-RBE) before joining Norwegian Air Shuttle Sweden in April 2008. The plane was retired in October 2009 and ferried to ESSP a few months later and is in use as a fire-training airframe with these small fictitious "Gustav Airline" titles. I couldn't get a better picture as I was immediately, politely but firmly, asked to leave.
