I checked all three M7270 modules I have here. The revision is stamped on
the purple handle. I have, Rev. E, Rev. H and Rev. K  All of them are etch
revision E.

The revision K board has the 1611H 21-15579 instead of 21-11549-01. All has
date codes in the range 77-80. I expect your boards to be later revisions.
