this is what the 2013 tardis looks like now   this is what the 2013 TARDIS used to look like

now here you can clearly see the difference with the new and old version of the 2013 dalek mod TARDIS the walls are different and that the walls used to be made out of iron and dalekanium but now they are made out of steel and TARDIS lamps in the next update make it so that there are two TARDISES one called 2013 dalek mod tardis A , which is the 2013 tardis with the steel and tardis lamps and then a second tardis called 2013 dalek mod tardis B , this one should have the older version interior where the walls are iron and dalekanium so this way we have a choice of the 2013 tardis interior.
