I think these are a couple pieces produced en masse for the export/tourist? market, done entirely by Moser in the style of Harrach, Josephinenhuette, etc., capitalizing on demand. Small and inexpensive mimics, if you will. Someone mentioned they're slightly different, and that's true, more so than you would expect of natural variation by one person. Look at the difference in the way the stems intertwine near the bottom - one vase is done clearly (over-under-over), the other is fudged. Lack of quality control.
When I saw the label this time, the first thing I thought is, hey! It's dated! Could the 7/22 be month and year? I think they could easily be later than turn-of-the-century.
One thing I was very keen to observe when visiting the Passau Museum was the verity of the generalization that Harrach had the color on the bottom, and Moser on the top. My impression is that it may be a trend, but it's far from universal.
