WH (Kriegsmarine) flute (ie. 'Bootsmanns-Flöte') that comes mounted onto its period chain as issued

This is a neat - and not that commonly encountered! - WH (Kriegsmarine) related personal-equipment-item: a silverish-coloured- and typical metal-based flute (ie. aka 'Bootsmanns-Flöte') that comes mounted onto its original 'attachement-chain' and that comes as issued and/or recently found. These flutes were 'standard'-equipment items for all naval non-commissioned-staff (ie. NCOs) and were used during exercises, training as well as during battle at sea. The piece on offer here is totally void of any marking or designation (as more often). The flute does show some moderate wear and/or usage but nothing too shocking: it was most certainly never cleaned nor polished and is just a bit tarnished. Simply a neat WH (Kriegsmarine)-related personal-equipment-item that comes in a nicely preserved condition and that is I deem accordingly priced!
