Family Estate - Can you help ID Glass?

Below are pics of items that were from my father's estate. Family lore is that  

they are Blenko pieces Some bought and some given to my grandfather Howard  

Slater when he photographed pieces for the catalogs for the company.  I've  

looked through catalogs and i think they are but as some don't have any markings  

on them, I'm not 100%. 

Can you please help identify and also value them if they are?  

Thank you so much for your guidance and assistance. 

Sincerely, 

SL
