Need help with makers mark

[Mark Smith]

 Recently purchased a Luster ware set from Japan at a thrift store. It has a very distinctive makers mark, but I cannot find the maker associated with the mark. Any help would be appreciated.

Hello,

Let me see... do you have a better resolution picture of the label mark?

It's kinda hard to determine.

Thanks:)

 Hopefully this is better, Its a crown that looks to have a S in the center, At first I thought it might be Nagoya Seitsoho , but havnt found one of theirs that looks like that.

Btw, this a link of some of the famous Japanese porcelain marks.

Might be useful for further reference.
