Nice coins! I had considered bidding on the top one; I don't think any of mine show that sword-looking symbol beneath the stylized Sri. Glad we didn't drive the price up on each other!
These are commonly just called "Sri ha" drachms, because it's just about the only thing we know about them. Sri is the flowy waterfall-like design in front of the bust that looks like a backwards £ with a bunch of extra lines around it; Ha is below - you can compare it with your Kashmiri Harsha stater. I'm not sure why he called it a Sri Va; that is a separate and very different coin.
It's a bit of a matter of debate whether these were a precursor or a concurrent "cousin". The Paruttha Dramma is attested through literature; according to Wikipedia's paraphrase of the contemporary document, the founder of the Chavada dynasty was able to assert independence from the Pratiharas by stealing a royal wedding dowry of 2,400,000 Paruttha Dramma and 4,000 horses, which he used to recruit an army. By that account, ought to be the direct precursor, but that clearly isn't the case... all "Gadhaiya" track coins are anepigraphic and strictly follow design conventions that were extinct on these coins; namely the flanking ribbons on the obverse, and sun and moon above the altar.
Anyway, I have a couple dozen for my study, but these are a bear to try to analyze due to the horrid strike on most specimens. For example, notice how your first one has a round eye, the second has a slightly almond-shaped eye, and Ron's has an eye that's a long slant. Yours are intermediate styles while Ron's is a late type, but the long slanted eye can appear on early types as well. Some appear to have been struck on very small dies while others were from huge dies... I can't make any sense of it.
