Hobbs or Not

The pictures above are all very similar pieces. The left picture is a documented Hobbs Wheeling Peachblow shaker, it came in two sizes.
The middle picture are a pair of yellow cased satinized shakers that are very similar in shape and size to the Wheeling Peachblow small shaker. The right is a very similar shape and size piece again of a cranberry satinized mustard jar.
So the question is, are they all from the same manufacturer and mould? The satinized pieces are the only ones Ive ever seen but Im certainly not claiming they are the only ones in existance. But it is interesting to think about if they are all the came mould and produced by Hobbs.
