Hi SBS7557R,
Thanks for compiling and updating the list so far, it's a very
useful reference to those not as readily in tune with the ground
movements. I have a little suggestion though, as more Wrights
get registered and deployed, can I suggest that you list the regoes
by perm service instead of vice versa, so that it might be easier
to read?
e.g. BRBP 60: 7505R 7508H 7509E 7516J etc
Thanks! :)
Agreed. 
Especially there will be 450 new Wrights and another unknown
number in future since there are still 300 plus VO3xes that needs
to be replaced in the next 10 years.
