Featured Makers Marks ?

I picked up this bangle which I thought was worth a closer look as I don’t recognise the marking on this bangles.One of the bands has Marcasite and the other has white stones that sparkle.The marks I don’t recognise and would like a bit of help to identify them.

 

Those might not be silver marks... could be marks of the jewelry maker. I'm not sure how many of the people who frequent the jewelry forum also come to this one. But eventually somebody will have an idea.

 

Thank you been looking at silver for years have had stuff from around the world but these marks have me stumped.

 

An interesting bit of info I read is that Vogue could possibly be the maker , estate sale said that they sign VO on their jewellery I wonder .The bangle looks like Vogue design and it certainly feels right but will see if I can confirm that type of stamp that’s on mine.

 

That looks like a stylised upside down Alpha and Omega.

 

I thought that myself , there’s a guy that signs VO for Vogue wondered if it could be that mark.

 

Possibly Vo Les Bernard for Vogue who signs pieces with VO .
