I checked a Rossie at the pro shop this evening and it looked identical to mine (font, spacing, placing, etc). I'm pretty sure mine is genuine.
After 9 holes I'm neutral on the Marxman, but I'm obviously still getting used to it. I had 18 putts, with two 3-putts. One 3-putt was due to a bad miss-hit on the first putt. It was my first long putt of the day and I wussed out. The last 3-putt was on the 9th hole and it was multi-level and I was annoyed at my route to the green (topped 3-wood, hybrid into a bunker, thinned PW past the green, duffed chip from awful lie, chip that rolled waaaaay past the hole to the lower tier) so I just didn't care at that point. I had a few putts lip out or just miss, so hopefully those will start falling as I get used to it. I've used a blade my entire golfing career so this is a pretty big change for me.
All that said, the putter is absolutely beautiful.
It took me a round or 2 to start to get adjusted to my Marxman, but I love it now. Hey, look at the bright side, if it doesn’t work out you’ll at least be able to recoup your investment with the deal you got.
