I believe the actual listing for the original box set is as follows: https://www.amazon.com/dp/B01IKH6O3Q/ref=cm_sw_r_cp_awdb_t1_xaW2CbTT4S3M0
The Swedish import could be a comparable edition, but I truly have no idea. The link I provided obviously shows the edition as out of print, with a few third party sellers with copies available.
EBay might be a better bet. Good luck!
