I was a former computer and electronics tech, and I am currently a medical student. I was unable to search for the LED through normal means. Most manufactureres use 800-940nm as their standard IR LEDs. The standard way of locating an electronic component is through: thomasnet.com
However you might need to order a vast amount from them directly.
If you do find an IR LED in the right range, please post the source. I will continue to look for one since I am interested in prototyping one for an experiment.

P.S. It might be that they used LEDs from Britain givene their location.

The 1072 nm leds are available in Europe.
here is a short list.
OPE5594S, 940 nm, 16 mW @ 100 mA, ±10°, 5 mm clear epoxy, datasheet
ELD-950-525, 950 nm, 32 mW @ 100 mA, 20°, 5 mm clear epoxy, datasheet
ELD-960-525, 960 nm, 26 mW @ 100 mA, 20°, 5 mm clear epoxy, datasheet
LED970-06, 970 nm, 4 mW @ 50 mA, 5 mm clear epoxy, 14°, datasheet
LED1050-03, 1050 nm, 2.5 mW @ 50 mA, 5 mm clear epoxy, 30°, datasheet
LED1070-03, 1070 nm, 2.5 mW @ 50mA, 30°, 5 mm clear epoxy, datasheet
LED1200-03, 1200 nm, 2.5 mW @ 50 mA, tr,tf=10ns, 30°, 5 mm epoxy, datasheet.
They are available from:-
Roithner LaserTechnik
Just google them or google the 1070 nm led info line above into google.
They seem to have all the wavelengths from 200nm upwards.
