St. Petersburg Propaganda over Royal Plate

This is a porcelain plate from the Gatchina Palace Service made by the famous St. Petersburg factory during the reign of Nicholas II in 1900 or 1908 (hard to tell). This service with a version of the double headed eagle coat of arms was ordered in 1820 & described in archival inventories as the “Service with the Coat-of-Arms & a Gold Band”. It was eventually transferred to Gatchina Palace for use there in about 1855 and since has been known as the Gatchina Service. The palace served as the primary residence for the Imperial family during the reign of Emperor Alexander III (r. 1881-1894) & for his widow, Dowager Empress Maria Feodorovna, thereafter. The service received frequent use & additions were ordered once again during the reign of Nicholas II (1894-1917) of which this is one plate. It is fairly simple compared to some of the other services I have seen but still very nice. Decorated with a variant of their coat of arms frequently used in the period of Alexander I (1801-1825), with the Imperial double-headed eagle with down turned wings & the shield of St. George on its chest & with a laurel wreath & torch held in its talons. Two gold rings around the rim to give it a bit more flair. And now for the interesting part. It was later decorated with a propaganda design including the year 1923 in large numbers and lots of smaller letters as well as the sickle and cog design. I have no way of knowing if this was done in 1923 or later but I suspect it was done after the original plate was rather worn so probably later to give the plate more value. No idea. It is still a neat plate having that combo of design which I ahve never seen before. The plate is in great condition with the wear to the gilding and armorial design. It displays nicely and is very interesting! It is marked with the under glaze green N II mark under the crown with the year mark of 1900 (or 1908) underneath as shown and two green dot along the foot ring common to the authentic pieces and still a mystery as to why they are there. The cog and hammer and sickle mark with the year 1923 in black next to the green mark. The plate is 1.125 inches tall and 8.5 inches in diameter.
