The inscription is written vertically. The picture is rotated 90 degrees to the left.
Yes, the first kanji would be supposed to be 小, but the direction of the two small strokes are wrong/incorrect. (Judging from the position of "hane" of the central vertical line, the direction of the whole kanji would be correct .)
The second one is 村.
The third one seems to be a miswriting of 守, or a Chinese hanzi 宁.
I can't identify the forth one. It seems that the writer inscribed the kanji incorrectly.
In conclusion, my impression is that it's a fake, or at least very questionable.
