As Kiz said, I don't think they're made, and if they are, I wouldn't buy them.
The original lo-pros didn't have the sharp flanges. For some reason they were changed at some point before the new "standard" wheelsets came out. I bought so many of the original 1008 wheels when they first came out, as well as Precision Master wheels in various lengths, that I have no idea when they were changed.
My first contact with the sharp flange version was in InterMountain flatcar, bought at a train show, that wouldn't go through my dual-gauge turnouts. It seems that, when MT sharpened the flanges, they took the material from the outside of the flange, so that while the back-to-back distance stayed the same, the wheel gauge was too narrow. And, since the gauge can't be changed, the wheels were junk, which was a big surprise to me. That was the first time I had ever had to change a MT wheel because it was out of gauge...
The new "standard" wheels run on my Micro Engineering code 40 flex track, so I'm satisfied with them.
