But on the other hand at a pound a minute or whatever, if you can afford the delay while it is ordered in just do so and charge buying it to the project.

Finding stuff is a mix of prior knowledge and luck, the company I work for used to be one of Siemens long haired R and D places, before it got bought and sold, and there is some history of us knowing roughly what is inside some of their stuff, and I always search for serial no and 'tear down'  to see if someone has cut one open on the web. Then it is just necessary to make sure there is a source in the public domain to point to first.


Of course if you have the cable and he lives near enough to borrow it, then it suddenly gets much easier.
