Nils Landberg Vase?

Hi everyone,
Is this vase a Nils Landberg vase? It has the same teardrop shape of many Nils Landberg sommerso vases I see online but it's not numbered or signed, just has the "Orrefors" inscription. Also the color on this one is a dark purple-red maroon unlike all the other teardrop Nils Landberg vases that typically have a smoky gray or blue color. This vase is on the smaller size, just a tad over 5" tall.

maxwellpark - I have had multiple cased glass Orrefors and your base looks right to me. There is the below link but I have no expertise to confirm the design is by Sven Palmqvist

Someone else may come along who knows for sure
