As Steve notes, I think most of these are Weber DCOE parts, but you have two different types of idle jet holders in there (and probably only one of them is appropriate for the DCOE), and two parts I don't recognize.
Top row, from left to right - 5 air correctors, 14 main jets, 5 idle jet holders with jets in them.
Skipping to the right side of the picture, in the upper corner of the picture you have a needle and seat, then a different type of idle jet holder (see the o-ring) with a jet, and two holders without jets.
At the bottom of the picture you have seven emulsion tube stacks. These consist of an emulsion tube, which is installed with a tube holder at the top, a main jet at the bottom and not shown in the picture, air correctors installed at the top of the tubes underneath the jet holder. It appears that there are two different types of emulsion tube stacks in there; the top three and bottom two are different from the dirtiest two.
There are two parts toward the right side of the picture, both a little longer than the idle jet holder and jet assembly, that I don't recognize.
Most of these parts are "calibrated parts", meaning they have numbers on them marking their sizing. I would think identifying the sizing would help sell them. That said, I hve no idea what the market may be for these things.
