The holy grail of Tru-Lins Jr presses is to find one with a turret threaded for Lyman's large dies, the .652"x30 dies used for the 348 Win, 50-70 US and some 45-70 calibers.
I have heard rumors that they existed, though no one that I know of had ever seen one.
The nice lady from the post office dropped by today with a box that had a new old stock turret, still packed in its original mailing box from Lyman, with just such a turret.
To say I am happy is putting it mildly.
To the naked eye you cannot discern the difference in size between the .652" die and the .607" inch die, till you try to fit it to the press, then the smaller die just drops in the hole.
