Help with ID on a Solingen 'Tree' mark

[Radboud]

The sword arrived yesterday, so can put up some more photos. My first impression is that it's a lot lighter than I expected, at 860 grams. The blade is 830mm long, but has lost a bit off the point.

It's also quite thin: (Profile / Distal taper)

• Ricasso: 35.3mm / 5.6mm
• 200mm: 30.5mm / 4.1mm
• 400mm: 26.1mm / 3.4mm
• 600mm: 23.8mm / 2.5mm
• 800mm: 15.3mm / 1.4mm

Although this profile is similar to the backsword blade on my 1796 HC dress sword:

• Ricasso: 32.0mm / 6.1mm
• 200mm: 28.9mm / 4.5mm
• 400mm: 27.7mm / 3.2mm
• 600mm: 25.2mm / 2.7mm
• 800mm: 16.5mm / 1.3mm

I'm guessing that the grip wire was redone at some point, possibly in the 1800s? Although the Turkshead knot looks good so it might be older but that seems unlikely.

All in all an interesting piece, even with the peculiar 'panel' on the blade. Will need to keep an eye open for similar blade profiles to compare.
