I have an old Ben Kenobi that will not accept any other kinds of light sabers due to some kind of stop built inside the saber tube where it should come out. This seems correct if I were using a DT saber and also why a normal single extended light saber. Does anyone know enough about the original DT figures to understand what I am asking about? Also, if I were to buy a quality REPRO would it fit in the same way that an original DT saber would or are the repros not an exact match to the real originals? I know these are rare but I figured someone out there would know what I’m talking about.
