Rock Island 571 & 579 Vise Differences

[dirtydogintex]

Anyone know the differences between Rock Island vise models 571 and 579?
Searches here and on google haven't been much help.

Earlier I was looking for a larger American made daily beater but $$$$ are causing the 'suitable' vice selection pool to become smaller and smaller....

American Made Vise..Daily Beater..Cheap.. Those words don't match up well. I've got one answer...Columbian..They take a beatiing...They made them big..And affordable.

On some series of Rock Islands, the second digit seems to be swivel (7) vs. fixed (9). The third digit I think speaks to the jaw size, but it is not linear. A 571 is 3" jaw, 577 is 6" jaw, for example. A 579 sounds like it might be a big'un, if you have any pics of such a thing, do share them. I have a 595 but that's my largest Rock Island at the moment. One day I'll snag a bigger one.
