Soft cream colored vase with lt grn interior- Red Wing?

This lovely vintage vase is 8 inches tall with a 5 3/4 inches x 4 inches wide opening. It is in nice shape t is some staining inside from flower stems I think. On the bottom in the glaze I can make out an 86 and the R as you would see in Red Wing. It is the same colors of other Red Wing vases I have. T are no chips or cracks.

Thanks for looking!
