My stock order of Duke PT's just arrived plus the PT jig.

The PT heel has the same L80mm x W32mm pattern as the Jester/Griffon but the metal insert worm drive track is a lot longer to give the greatly increased length adjustment.
The PT toe has a L46mm x W38mm pattern compared to the L31mm x W36mm of the Jester/Griffon.
Here's the PT mount in red alongside a Jester/Griffon mount in black, both at 300mm bsl and both mounted on the line. The heel holes are identical. The PT's toe locations straddle the rear toe locations of the Jester/Griffon by 15mm and 16mm so there's more than enough room for a conventional mount and sufficient room for a QK/BF mount even if the original mount was with inserts.

It's a pity that there's 2mm difference in the mounting width at the toe but if you wanted to use one of the pairs of Jester/Griffon holes then you'd end up +15mm or -16mm off the mounting line (assuming the same bsl) so very few will want to do that. But if you did want to do it (ie when there's a difference in bsl) then if you mounting the PT toe with inserts then the insert would enclose an original conventional mount and you'd be good to go.
So kudos to Marker for giving Jester/Griffon users the ability to upgrade their bindings without incurring any mounting hassle.
If anyone wants me to check the mounting hole compatibility with a different binding then advise the make/model/bsl of the existing mount plus the bsl for the Duke mount (if different) and I'll overlay the jigs to check.
