There were some for sale in the for sale section (suprise) on here not so long ago, they may still be up for sale,
I saw a set the other week that appeared to all be on one 'plate' as if hot wired out and you had to finish them off, there were no handles so i guess you had to fit them into a holder and they were around 5mm wide, not like the ones in the link above,
I think they may have been german and possably hpc but im not sure, were these the same thing but for a differant lock?
Do i understand this right in that you would use CGP's as a kind of jiggler but with a separate wrench?
Up untill now i though they were used as a tension as well

like a jiggler set for cylinders, oh well you learn somthing every day, perhaps its time to read the threads on them again.
