An officer's cockade, moreover, the figurine depicts a junior-officer, and for junior-officers the cockade was then trimmed around the perimeter with a twisted cord in several rows, and in the center, in a field of alternating orange-black zigzags, the monogram of Alexander I was embroidered.
In your photos, the officer's cockade below is shown approximately correct, but the shako in the photo is not Russian, but Dutch.
This is the shako of the junior-officer of the guard.
This is a senior-officer of the grenadier regiment, his cockade on the shako was sheathed not with cord, but with round sequins. Compare the photo of the senior-officer's cockade.

Wrong! See color scheme for shako cockades in the infantry from 1811, which were used in 1812.
Here is the translation with decryption (do not forget that these colors apply only to soldiers in the rank of privates):
View attachment 451018
the Grenadiers have red cockades (in the first battalion they are full red, in the second with a dark green lower segment, in the third battalion with a yellow lower segment);
the Shooters have yellow cockades (in the first battalion they are full yellow, in the second battalion with a dark green lower segment, in the third battalion with a red lower segment);
the Fusiliers, Musketeers and Jaegers have two colors (in the first battalion they are white with a dark green core, in the second battalion they are dark green with a yellow core, in the third battalion they are red with a yellow core).
Well, they weren't always oval, before 1809 these cockades were round. And at the maritime department, round ones were preserved until the uniform reform of 1817 (but this does not apply to the figurine of a grenadier officer for 1812).
