I'm always the one who says things don't look like decorator pieces or that I think they're for the native market, etc; I was thinking I'd give it a rest for a minute, but yeah, it looks pretty "real" to me, too. Smaller than the one in the book, and with a differet suspension, though.
BTW, I think you'll be pleasantly(?) surprised; I think the dicolouration on the blade is rust/patination that can be easily cleaned to smooth grey patches with probably some pitting with fine steel wool and runny oil, and the areas in between look smooth and fairly original though standard photo disclaimer etc. Also, though I'm getting more hesitant about giving out hints, (
), I think the discolouration is likely following the layers of forged lamination (and it's possible some of these areas may be forging flaws, open grain, etc.): I doubt this is a wootz blade, but probably layered steel.
