I found the Kursk maskirovka stats from the Cross´ book Kursk:

To deceive German aerial reconnaissance during the build-up, at least forty false airfields were created, complete with dummy aircraft,runways, control towers and blast pens.These were repeatedly bombed by Luftwaffe. Dummy tanks were assembled on both fronts to stimulate armoured assembly areas;on Voronezh front there were 829. special maskirovka units ( if it is the number 829 or the 829th I am not sure as it has the the point after it ) and combat troops were used to give the fake airfields and armoured laagers every appaerance of activity.Along the front lines the defence lines were dotted with false gun positions.And on some sectors the main defence line lay behind a complete dummy defence line in the expectation that the latter would draw heavy enemy fire in the preparatory phase of the battle. Sixth Guards Army sought further to confuse the enemy by building a network of dummy observation posts which were manned by experienced reconnaissance troops.
