Firstly can I say a big thank you for your warm welcome. Being a member of other forums this board certainly comes across as a friendly and enjoyable place to be. Credit to you all.
The advice is fantastic and very welcome.
Before I continue, rest assured the whole blade - with fittings removed - was lightly oiled with mineral based motor oil ( It's all I had... ).
Some of you have been very kind and given me answers to questions I was going to ask in terms of going forward, however I've now become slightly obsessed by all of this and have more questions - sorry !
1) How accurate can we be in the blades origin ?
2) What is the best way of ensuring authenticity ?
3) Does the blade have any value ?
4) Should I / Can I ensure against that value ?
5) Is there a way to reunite the blade with the original owners family perhaps ? It seems the right thing to do and would make a great story / project for me.
6) What would you do if it was yours ?
Here are some further images of the blade as requested. The blade length with all fittings removed is 25 Inches on the nose ( as in exactly!! ). As with the first set I have adjusted the contrast in order to highlight the details.
I have also added an AA battery for uniform scale comparison.
Thanks again everyone.
( PS - I also have a confession to make. As a very small child I used to sneak the sword out of the house and attack trees etc with it. It felt awesome!! )
