Two more examples; one with the 'large' unit number and the other with the 'small' unit number. The large unit number is for another Guards 'Katyusha' Regiment and the small unit number is for a Guards Motorized Rifle Regiment.
Two photos from the 2010 parade showing original Guards flags being used...the first photo gives a very good indication of the color of the thread used for the lettering.
Not from "Guards" unit flags, here are a few rare images of Lenin with Stalin from unit flags. The first two are from state security unit flags awarded postwar and the third is from a tank unit during the war that had a 'field made' unit flag given to them by a local Komsomol; the third flag was never in my hands, so sorry for poor quality shot.
