Moorcroft Vase with Leaf & Berry Design

I have what appears to be a Moorcroft “Leaf and Berry” pattern vase and am looking for a little more information on its value/authenticity. The base is impressed with a stamp mark and facsimile signature of “W. Moorcroft” along with “Potter to H.M. The Queen” underneath the signature. There is a “Made in England” impression in the base as well. The “W. Moorcroft” signature seems to resemble the Moorcroft markings dated from 1928 to 1949. It has bright, colorful leaves and berries over a cobalt blue background. The dimensions are (approx.) 6 ½” (15-16cm) tall, 2” (5cm) vase opening diameter and 3 ¼” (8cm) base diameter. There are no visible cracks only a little wear/scuffing on the rim of the base.
