156 Engine number location?

[Dean in Scotland]

Hi, I have a year 2000 UK spec 156 1.8TS that had been sourced from Europe and am having trouble locating the engine number. The manual states that it is at the right rear of the engine on the gearbox side but I can't find it anywhere and the manual "picture" is rubbish. Surely the number should be in a visible position or have Alfa just been awkward and put it under the plastic cam cover or something?? Can anyone supply me with a digital picture of where it is actually located PLEASE!
Thanks, Dean
