I have not completed translations of the right wing as yet and am not sure if Yakovlev gives the historical data of what was each room c1840s-50s. The study of Nicholas I by Hau 1845 is #52 Study English Suite on the Yakovlev floorplan. The Drawing Room of the English Suite #51 retained the similar upper wall antique frieze and ceiling cornice as it was c1840s. It is the same as in Hau's for #52. The fireplace in #52 was retained also.
In Nicholas I study there were shelves of mounted cavalry figures under glass that were moved c1900s to the Small Library #2 and Great Library #3. I have often wondered of these and apparently they were of papier-mâché which surprised me as I had thought they were lead. No wonder they were under glass domes.
From a memoir of the 1850s of Nicholas I:
"...One of the curiosities of his palace was a room containing the uniforms of every regiment in his army, made for himself to wear, on occasion of special visits to the different barracks. Another object manufactured for Imperial use was a dinner service of Russian porcelain, with the devices and uniforms of every regiment in the army; and in the private Imperial Cabinet at Tsarskoe Selo, mentioned above, I remember being struck with the bald simplicity of the furniture and decorations, the latter being nothing more than an immense series of papier-mâché models of cavalry soldiers..."
