Head space field gauge

[WHG]

Where/who can I purchase a military spec .074 field gauge from? I purchased a Forester field gauge thinking it was .074, but it turns out it's .070.

WHG,
I purchased the same gauge several years ago. Was advised to cut a piece of .004 feeler gauge to make up the difference. Hold in place with a smear of oil when measuring.
