Yes, it is the skeets gauge i was thinking of. I used to have one but upgraded to a hosford gauge. I had thought it was made by manson.
I see it looks like brownells doesnt even sell the skeets gauge anymore.
I think i only paid $100 or a little more from brownells for mine when i bought it. And insold it for $75 to a friend just this past hear when i upgraded.
The only limitation i ever had with it was not being able to do 10g. And, if measuring 16g, i could not not get it into the muzzle of a full choked gun.
