This rentjong was definately on a fair in utrecht last year without scabbard and without provenance. I was there for 2 days and seriously considered buying it. the horn hilt and the missing gold piece are 100% recognisable.
So you could have just replied that you did some investigation and found a provenance.
Strange that instead of that you get both defensive/offensive and personal
Maybe better to remain factual. 'can't beat the facts' as you say yourself
