First, an apology. A corrected photo has been posted.
Using a Starrett depth micrometer, I got new measurements.
To the nearest 0.001, my two Marlins are 0.130 deep. My Savage is 0.115 deep.
I need to retire my old dial caliper. When the depth micrometer is set at 0.130, the caliper measures it at 0.140.
