The Dnbforum logo font

Does anybody know the name of the font which is used on this forum's logo (on the top banner)?

I'm pretty sure Pendulum used this exact same font in their 1-minute teasers for "Immersion".

I gotta say that it's a great-looking font and I've gotta have it. :crazy: It must be available somewhere, in fact, it's featured in at least one episode of Thunderbirds. (Also check out the crablogger.) So, wow, this font must have been in circulation for at least 50 years! However, all my searches for "pendulum font" and "immersion font" and suchlike have ended in failure. So, any help locating this font (as a TrueType, preferably) would be greatly appreciated. ;)
