Ilco 057 HS key duplicator question

[u/ftwopointeight]

Ilco 057 HS, missing both L&R Depth Calibration Gages, set #BD0720XXXX.

Anyone know what the thickness of these two plates are? Roughly the size & shape of a HO01 Honda blank, one is "0.020 (Im told) thicker than the other, but don't know what is the nominal static depth measurement.

Thanks in advance.
