Just acquired a Willow Leaf sabre ....my first 'genuine' Chinese weapon. I want to thank Josh (Stout) for his advice, greatly appreciated

.
Blade spine has distal taper 8mm at forte 1mm at tip
Blade width 42mm at forte to around 40mm near the tip.
Damaged and loose guard, the hilt/pommel is also slightly loose (a light peening would tighten it again ...but not enough to secure the guard ...leaves a gap of a few mm's )
All fittings iron/steel. Scabbard also appears to be original, wood core with a textured leather/rayskin with iron /steel fittings.
Ideas as to age, restoration advice and other comments greatly received, thank you
Kind Regards David
