Details are virtually identical to those of 3rd Battalion, The Reval Infantry Regiment less the epaulettes, which in the case of Murom Regiment were white.
In terms of the elite company, that means red over yellow pompoms for the grenadiers and yellow over red pompoms for the sharpshooter platoon.
The sword knots of third battalions are distinguished by a red central band, edged red in the case of the elite company and white in the first company. As with the other line companies, the first company sport yellow within red pompoms.
I hope everyone is enjoying their (Easter) long weekend...
