Nemrod did go bust but I have heard rumours they are starting up again. Your best bet is to try a Spanish spearfishing supplier (Nemrod was a Spanish company) who sold the old airguns, Clipper series, Galeon series etc. etc. and see if they can scan an old manual. Try Alitan Sub (alitan-sub@alitan-sub.com) as they used to stock most of the old Nemrod series of air-guns. If not, try a Spanish spearo forum like
www.pescasub.com or
www.medfish.com and ask there. Good luck.
