Unfortunately, the source doesn't say what year this budget came from. There are some hints though. The T-33 is a precursor of the T-37A tank. A prototype was built in the spring of 1932, but the tank did not do well in trials and was not accepted for mass production. Presumably, this budget was composed shortly before the decision to not produce the tank was made. The T-41 was also an amphibious reconnaissance tank, which underwent trials in the fall of 1932. The fact that Grotte's TG-1 tank is absent from the list altogether and the T-24 is only listed in the spare part production section agrees with this timeframe. This seems about the right time that something like a superheavy tank that cost twice as much as a T-35 would still be considered viable.
