So how long this two screws construction was in use?

Ten to one that until 2003.

But the maximum time coordinate that we have today is April 1994.

Take a look at this excellent 4^th class that was awarded to Takagi Yoshihiko on April 4, 1994.

100% Agree! The screws were used until 2003 - and continued onto the current form of the Scared Treasure. Why would they change from screws between 1994 and 2003 and then change back? Doesn't make much sense, so I think you are right.
