Ashtray's?

Hi Fellow Collectors!
I have here what I believe to be ashtrays, but the oddity of them leaves me not sure. And that's where you come in....if you know anything about any of these items, I'd love for you to share that information with me. It will be much appreciated!
The cut glass (crystal?) has no stand out cigarette rests. But it has three, of what I believe to be snuffers? They are rather large to hold a cigarette as the cigarette leans way over. But they appear to be about the perfect size to extinguish a cigar to save for later. All thoughts and comments appreciated.
The porcelain one does have obvious cigarette rest just inside the rim, but the rim itself is undesturbed by the rest. I tested the rest and a cigarette does sit there as if it's made for that. Also, I can find nearly nothing about Mascot China. Any thoughts?
And the plastic one is made by Waverly Products. I have found many ashtrays made by them, but none look like this one. This ashtray? has very wide rests for maybe a cigar?
Thanks everyone! Hope you're having a great day!
