Acid Etched Vase ?? Fenton Ming

I picked up this Acid Etched Vase a while back at the GW and have been trying to figure out it's origin. The only thing I have found that looks like it is the Fenton Ming Pattern, but I have not been able to find anything similar to this shape and I am not sure about the bottom. If anyone has any information about it I would so appreciate it !! Thanks !!
