This has been puzzling me, at first glance it looks like a classic Swiss such as Helvetica, but it's got differences on the 'e' and 'a' terminals a bit like a modern Swiss-a-like such as Arial, yet I can see, especially from the 't', that it isn't Arial, it also looks a bit like Franklin Gothic but isn't.

My guess is they customised Helvetica but I'd love to know for sure

Anyone?
