DDR/Russian sport speargun spare part and bow

Among the listed Hähnel air rifles are also these 2 harpoons, as far as I remember, my brother said one comes from DDR combat swimmers, it is complete and just needs restoration, the other is a Russian make with only the shooting arm present, missing arrows and accessories, spare parts. Then there is an old bow here, only what is shown in the pictures is available, nothing more. If interested in any item, make me an offer. If shipping outside the EU worldwide, shipping costs increase. If shipping is cheaper, the remaining money will be refunded. Price negotiable, just make me an offer for what interests you.
