With no makers mark, I wondered if anybody may have a read on whether or not this looks to be a Nambu Tekki piece or not. I've not seen a pattern on the bottom like this before, generally only smooth. Anybody familiar?

This one looks very strange to me, also the patterns look a bit non-Japanese to me.
I agree, it’s a bit of a head scratcher to me, I have not seen a bottom of the same style before and couldn’t tell well enough from the pictures if there was a tell tale seam running vertical to indicate a mass production two piece mold.
