I *think* this is one of the Libochovice patterns which isn't shown in the catalogues we've seen so far. It matches the candlestick 2021, with which I've seen it plus a ringholder, probably 2024, and pots 2022 and 2023 are also a match for these items. I'd have expected the tray to be 2020 based on their normal system, but 2020 is a slightly different pattern and a different shape. In fact 2020 is another oddity, as the catalogue shows the same shape as a tray I have, but with the same base pattern as yours is... see pics below for comparison..
