Badges combining unit insignia with serial numbers, in the style often used by 7th Armoured Division. The sheet includes 22nd armoured brigade's combined stag's head marking with unit serial. (22nd was decidedly unusual in using it's own badge as well as the division's, so the desert rat badge was also painted on separately, at least when markings were applied at all....)
It also has combined serial/desert rat badges for the amoured recce regiment (often carried centrally on the hull of their Cromwells, just below the turret), and the infantry brigade. These were very occasionally seen in Normandy, but are more use for a *very* late war force - photos of 7th Armoured units in early '45 very frequently show them.
