I have always assumed that Scottish information did not have access to Radar. If this is the case presumably any traffic information is derived solely from traffic reports.
Surprised to hear IO540 say he has never been offered radar traffic info on FIS . I found this to be far more common than not.
Under the new system I find that controllers providing BS simply advise that you have "temporary traffic service", pass you the traffic info, and then go back to BS again
