David these are products made by Precision Cam Drives of Australia. The brand name of the vernier is Rollmaster, and it has a West Germany made Iwis timing cahin, thats a $40 timing by itself, consider to be the best quailty chain in the world.
The balancer is Roamac, it a all steel unit, so it doesn't crack like the cast iron stock ones, and it degree for a top timing pointer.
I use these peices in alot of my quality rebuilds (street and race), for example Drew's engine has both, and so will Ray's.
