Red Wing Anniversary Line shape B2315

I have a dark blue and ivory Red Wing pottery vase that is about 11 inches high and 6,5 inches as its widest point. I know it is older than 40 years but am not sure of the dating. It has two openings into which flowers can be placed. The marking on the bottom states Red Wing USA and I believe the letter/number B2315. Any information you could provid regarding this vase would be greatly appreciated. Thanks Rachel
