I have a couple of Jrs, one's even an aluminum model that I mounted on a small portable table. Mine
had the priming arm but not the tube system. I don't miss it at all, prefer the Lee Auto Prime. Yours is a bit older than either of mine but it looks good to me. As long as it moves freely and acommodates dies and shell holders you're good. I like my tools with a bit of character but that shiny new paint job above does look purty.
Either way you have a fine press and when you put it to work you'll make your dad proud.
