Forum member Grey Havoc has kindly reminded me that Wikipedia gives a very detailed list of Boeing's customer codes (i.e. the extensions that follow a particular airliner model number to indicate the airliner or agency that ordered the version).

It can be found here: http://en.wikipedia.org/wiki/List_of_Boeing_customer_codes
