Before Scratch 23May05, you could stretch sprites. As it turns out, the code that stretches the sprites was never removed and any Scratch version before 2.0 can be forced to have stretchy sprites. However, trying to load the project in Scratch 2.0 or higher will set the size to the horizontal stretch. Edit: Saving a project with the stretch blocks in 01Oct04, loading and saving it on 26May05 then loading it with Scratch 1.4 restores the blocks
