May be miles off like.
No idea about Percy Main, but I don't think it will be too hard to work out, if you use the other services given as examples at Chester and Stanley.
I don't know much about Percy Main but I am pretty sure that the Cobalt Connect and Coaster services are in the same unit. I have seen a few Coaster drivers on the 19 and vice versa.
