PA404A 1009 ... or is it?

So the "old" PA404A that was originally knuckleheaded *and* unable to cut out lower than 3.5 PSI when correctly set for .5 cut in + 1 differential was replaced by the "new". Looks like someone in Mexico ran out of the correct chassis and threw together a run with the "cut out" labeled scale? Or am I missing something here? Anyhow, bench tested the new and it was close enough, then calibrated the old and will keep as spare or high limit if I ever decide to add one.
