Basket hilted swords

[Bakerbarang]

I'm new to the forum and am an experienced collector of British Ordnance Flintlock weapons. My experience of swords is, however, very limited and I am seeking to learn from the obvious experience represented in this thread.
A few weeks ago I stumbled on an add on Craigslist - a person was selling three swords. Two of them were tourist trinkets (not actually swords), one appeared to be a British Victorian sword with the grip broken off but the third was a basket hilt. The Craigslist photo was terrible with the swords being almost silhouettes, but the outline of the basket hilt made me suspicious that it wasn’t junk. So, I met the person in a dark and gloomy house but even in the darkness I could see enough to know it was a real sword. I purchased it and took it out to the car in a garbage bag where I could have a real look in the daylight – I was not disappointed. It is a nice sword but I’m still not quite sure what I have. I was initially thinking a 17th century blade with a late 18th century hilt. The hilt, at first, looked like a later style but the presence of small curved quillons and short langets tends to point to something earlier. Am I right here? The more I looked at it (the overall condition and pommel riveting) it looked original and un-messed with. A gentle clean of the blade revealed markings which look old. So, do I have a 17th century Scottish sword? Internet searches reveal very little to guide me and the only text reference I can find to anything similar in form are on page 61 and 62 of Mazansky’s British Basket-Hilted Swords. But all of this represents my guesswork. I'm hoping some of you can guide me since the sword learning curve is extremely steep and Im having trouble putting this sword in some sort of age and ethnic context.

Any ideas/advice would be appreciated?

Anyway, I’m thrilled to have found this sword in a pile of unrecognized junk on Craigslist!

Thanks for your time.
