Unfortunately no 10 gauge Craig,
I think there may have been a Grade 7 10 gauge or possibly a 12 gauge Magnum sold at Julia’s a number of years back, other than that, I’ve never encountered a Grade 7 10 gauge.
According to company summary provided by Keith Houghtling for Walt Snyder’s book, there were approximately 22 Grade 7 NID’s produced. This does not include earlier Ithaca models.
Me and a friend had 5 together and we thought pictures were necessary.

PS. There were 2 28 gauges and 2 410 Grade 7’s, I wonder where they are
