What was the value of the resistor (measured)
In theory, there is no difference between theory and practice. But, in practice, there is.

Umm... I don't know. It's somewhere in the wire wool for cleaning the iron. Too small. I think I've got another of that type so I'll check when I can dig it out.

In case anyone was wondering, I'm having trouble with my meter. It's a 121GW EEVBlog meter and even with a known capacitor, I'm getting odd results. I'm concluding I just can't get this sorted... but I've got another problem to get to grips with, however I'll take pictures tomorrow and save that for another post.
