ID these powder charge bars?

[shell70634]

Found these in a box of reloader parts. They are 3/4x3/4x5 1/2. Very similar in design to my star powder bars but huge. Any idea what they fit?

The red ones look like MEC.
They still have charts to tell ya which one does what, and which bushings fit for the powder charge.
The shot charge weight is labeled on them, a bushing drops in for the powder charge you want.
I got away from shotguns years ago, but the MEC bars and bushings might also be current production.

The two adjustable ones are OLD. They might for a old Herter's or something.

the two brass ones are for a Star Reloader. They are adjustable and they are worth at the least... $75 each.

After a closer inspection the one in the back may (or may not) be a rare one. I have seen many of these but not one with the shorter black pillars... it may be from a Star Rifle Machine or from an early Super Star 223 conversion. I know a lot, but I'm no expert. The great news is... I am sure somebody with more knowledge than I will be right along to set me straight... or somebody may have replaced the pillars... hard tellin', not knowin' :-P
