Here are a few maps and drawings of Tuva.
Soviet Military maps http://mapn46.narod.ru/map1 for the maps in square N-46 http://mapm46.narod.ru/map1 for the maps in square M-46 and so on for maps in the scale 1 : 100 000
You will find maps in different scales here http://mapn46.narod.ru/index.html for N-46 and so on. The maps are from the Soviet era but the best to get. For Tuva you need the squares N-46, N-47, M-45,M-46 and M-47
Or try http://www.afanas.ru/mapbase/ you will find the same maps but all of one square in one zip file.
