Unknown Glass Marking- Have You Seen Me?

Howdy all, posting a few pictures of some things that I just got fed up with not finding any new info to help identify them. Thought maybe I would ask for your help This is a a very pretty lavender vase that looks like it has aventurescence. I have been unsuccessful in locating any info on the sailboat shaped marking on the bottom. Could you have a look and point me in the right direction on who made this?
Thank you!

 

It's a glass cone, not a sailboat. However, I have no clue who made it: I had its twin a couple of years ago and never managed to find out who dunnit!

 

I've seen this logo somewhere.
Anyone have the book 20th Century Glass. Mine's at the store and I'm so tired I'm not sure I'll remember to look.

 

I've got it, but it's not in there.

 

Thanks for looking.
I was just searching glass logos. With no luck.

 

You might ask the curators at Corning Glass. https://www.cmog.org/about/staff-biographies

 

This is the one I had.

 

ABSOLUTELY NOT sure this helps any, but........positive + negative, although I must say, it almost doesn't look like it...

 

I'd say that's a match !!

 

Identical, isn't it.

 

I just know I've seen that mark before - and likely, here!

 

I did post it here a few years back.

 

But we never found out who used that mark?

 

Nope! You'd think a glass cone would be obvious.
