Slight issue when using a medium base with turret ring. The identifier socket is too loose. The turret marker raises the ID cardboard so that it falls out at the slightest move. On the small base the plastic stands out more so that the ID is held firmly in place.
Put a Y wing next to K wing with turret marker, look at them side by side and you can see why. The small base has about an extra mm.
As well as this there is an issue when basing IG88 on the medium bases. Because the mounting point on the ship is different to the standard mount, it's triangular, you have to use the mounting peg from the 1st edition which falls off the medium base if you look at it the wrong way. Time to super glue the peg in.
