Sanyu?

I'm so in love with these pieces I could stare at them for hours. One ashtray- super heavy and a sugar bowl with a stainless steel lid. I've been trying to identify them and after some trail following I think they might be Sanyu. (??) Hoping racer4four might be able to help me out. :) I don't really know enough about glass description to provide intricate details. They have no stickers or ID anywhere. There are a few little bubbles in the glass here and there (particularly in the sugarbowl), but the bases are clean and there are no scratches. I found one at a boot market and the other in a second hand store in the same town. What a moment when I found the second one! The sugarbowl was so different to anything else I'd seen around- I was over the moon when I found a matching ashtray. I had a dream that they were with a vase at some point. I hope it was prophetic and that I'll find it soon.
