I didn't know that every machine came with a set of ALDs but you are right that a lot of /40's were sold stateside. My dad was re-posted directly from Hursley to Poughkeepsie in '65 which I was where some (or all?) the /40s were assembled. One of the IBM Journals (75 years?) has a large colour photo of a row of 40s on the final assembly floor at Poughkeepsie, everyone in it striking that characteristic 60s/70s IBM-photo-pose, eg. someone leaning over a table, another reaching for a console knob, one changing a tape and at least two people earnestly discussing a printout.
