大正時代のむらさき切子皿？Anybody know what this is?

I just bought this glass plate this weekend. I am guessing it is kiriko cut glass, from the Taisho Period (1912-1926), but if anyone knows better/more, I’d love to hear from you. サイズ：φ24.5cm/4.5cm/45mm 素材：ガラス There was something similar on sale here, but I prefer this design. It’s got a kinda masonic-bird-Art Deco thing going on. I also like that the round parts aren’t perfectly round, and the glass has bubbles in it, and the dark brownish-purple colour is shibui (sorry, my photos don’t really do it justice). Anybody know where it might be from? I know there is a difference between Edo, Otaru and Satsuma kiriko, other than the obvious geographical one (I once learned, but have forgotten). Thanks!
