Here are a few of the pieces that Siman looked at:
W301. Simon pointed out that the big belly on this piece is typical of the 13th Dynasty. The inscription is the standard offering formula and mentions a person called Minaa. The piece is made of granodiorite so is an elite piece.
W5291. The piece on the left is also of granodiorite and thus an elite piece. If you view the statue sideways on you would see that the man is kneeling, as is common with other statues showing figures holding vessels. No exact parallel to this is however known. A little more can be found out about it here.
