Cute Little Cobalt Blue Glass Pot/vase with a Mark

This is likely an realistic request, but I hope you all can look at this little glass vase and see if you recognize the mark. AI says it's probably an unknown glass artist who scratched their initials on it. But it's a cute little thing and very well made. Note the ribbing in the shape. I got it at an estate sale and it was filled with tiny little faux blue flowers that looked worse for wear so I pitched them. She had it in a little arrangement with some cobalt blue candlesticks at the end of her mantle. The initials look like HFY 92 or 72. It's wee (as the Scottish say), measures 2 1/4" high and 3" wide. Any ideas?
