This is probably heavily customized, but can anyone suggest something similar?

Hi John. There are lots of distressed Couriers out there ...
this one comes up first with a google for "typewriter fonts"
http://www.free-typewriter-fonts.com/
Whoever did this one should've rounded
the cap and join when they outlined the font.
True ... also worth noting, the designer did the
repeated letters, same distress marks thang.
a fun thing to use to distress stuff
is FilterIt's Fractalize Filter.

I'm sure he could -- he designed them.
And who could forget Chandler 42, from PsyOps?
