Retired Bus Numbers Needed

[sw4400]

I'm trying to make a list of the Bus Numbers retired from the following bus types:

-TMC RTS(4400)

-Flxible Metro(5300)

-Flxible Metro(6000)

-New Flyer(5800)

-NOVABus(6400)

NABIBus(7500)

This is a lot to ask of anybody, given how difficult this job would be to find out.  But if anyone knows(as close as possible) what bus numbers are retired, I would appreciate your help.

Thank You,
