4 Queens 9/7 DB progessive machine question

On the vpfree machine listing for Four Queens it says that there are 12 uprights with 9/7 DB on them that are progressive quads only for .5 and .25. Are these machines linked with the bar progressives? Also is there 9/6 DDB on these like the bars?? In all of my time visiting 4Q I haven't looked for or played this group of machines near the pizza place, but would like to try them especially if they have DDB on them! More comfortable than bar stools.

There are 9/6 DDB and I "think" they are linked to the bar. They might be there own progressive.

Outstanding!! I will put them on my list of "must play" or at least check-out on our stay!!
