My Lyman is the older orange one. It has the knurled ring that slides off the keepers to hold the tool head down, didn't know they changed to a bolt. It also has the same style flip out primer arm that the Lee uses, although I hand prime with an RCBS or Lee. IIRC an extra turret was $20.
Depending on what your loading for you can have dies set up for 3 different calibers all on the same turret.
