[HBR] Jackson Brothers "replacement" for Eddystone 598 dial?

[C Eus]

All:
I found this slightly curious.  The discontinued Eddystone 598 (not to be
confused with the more popular slide rule 898) appears a lot like the still
manufactured Jackson Brothers dial shown here:

This drive possesses a 36:1 drive ratio and should be suitable for HBR
purposes.  JMHO.
