Satsuma Vase?

My mother has this pair of vases. They are mirror images of each other. There is raised painting on the vase. There's a basic floral image on the back of both. I've included an image from the bottom of both.

After all extensive search online, I've only found one vase with a similar structure/shape (handle design, and basic structure 98% identical).

Any help with the time period, artist, manufacturer, etc - would be greatly appreciated. I may be in for an adventure in tracking down the information.

Japanese Satsuma Vase. Many of these are Kyoto and would date to 1930 or later so i would guess early to mid Showa period for this vase.
