Unfortunately, the older OG Website (oldgloryminiatures.com) does have photos of most of their WW1 figs, but not of the Russians. I would agree with Carlos that they are slightly better than the standard OG castings, but I'm not sure if they're worth it, to be honest, as a friend advises me that even these are covered with loads of flash and far too much work to be worth it.
That said, some of their WW1 figs are really quite nice, by OG standards, honestly. And your mileage may vary. Fortunately, as the Russian uniform did not vary dramatically during the course of the war, there are a few Russian ranges worth investigation beyond Old Glory. Musketeer does some beautiful stuff, for instance, and the old Battle Honors Russians weren't too bad.
Unfortunately, very few options exist for the Russians on the Western Front, who wore Adrian helmets. Hopefully that will eventually be sorted.
