Featured Large Ludwig Moser Amethyst Vase; Deco?

This is ~19 1/4" tall, with a rim diameter of ~8 5/16", foot diameter of ~4 3/4", the gold band is ~3" high. Weight is ~4 1/4 Kg (9.34 Lb)
The rim is ground, chamfered in & out, an' polished; I'm surprised that there is no damage to it, or anywhere else; the foot has some honest wear, but no pontil.
As you can see it is really needful of washing, as drips, hand & fingerprints etc. are everywhere on it, inside & out; all I've done is dust the ages of lint an'debris from the inside, after years of sitting upright on the floor where it was displayed/neglected. Its size an' weight make it challenging for me to handle, especially when it will be wet an' slick with soap! I'll persevere, though...it'll gleam soon. It was essentially a gift, as the fellow wanted rid of it; $10, an' he wouldn't take the $20 I offered but gave me a ten in change!

I have an age sense of 1st quarter 20th C...but I'm guessing. Is it correctly Art Deco, or? Image search has lots of roughly similar shapes an' patterns, in amber as well as amethyst, by Moser; but I've found nothing as large. Probably time to check eBay for past sales. Your comments an' suggestions are sought, an' most welcome. Thanks for lookin'!

 

Decoration may be Trojan War-inspired.

 

Yes...looks more Greek than Roman.

 

Fantastically beautiful vase! Good price too.

 

Nice lump. Certainly got some age with that wear on the base. And i reckon youre right, art deco, 1920's 30's

 

If it is Moser glassworks crystal it looks like the key words you need are Fipop Series, introduced circa 1914 and Oroplastic, regarding the frieze. I saw one seller spelling it Oroplastique.

Snooping around the internet I found one with a Bohemia Czechoslovakia sticker and another one with a French Baccarat sticker... So, could be something hinky going on here.

The link below is a springboard to the Moser Glass customer service email. They say you can send pictures and they will ID for you, as in yes it is Moser or no it isn't.

Great...Thank you, Laura!
In my initial research I noted the word Oroplastic but didn't recognize the meaning as it wasn't further described.
I'll use your Moser CS link just to be sure, but feel pretty confident about what it is.
I'm gonna wait for warmer weather to approach polishing the grime from it...it's way too large for my kitchen sink, an' I have a large wooden table outside that will afford better security as I work at it.
