Hello Baz69, due to the very distinct ring holders, the scabbard bands and the special pointed acanthus(?) ornament at the scabbard end for me this scabbard is clearly an ALCOSO product. Normally ALCOSO navy scabbards also have the short/long lightning ornament at the scabbard end and I don´t know why th short lightnings are reduced to only spears. Perhaps the ornament was done by an unskilled worker or the worker wanted to save time, we will never know.
Best regards,
