Can someone tell me the diameter of a 410 gage Skeet choke?

the diameter of a 410 gage, Skeet choke? (I have no way to measure one.)
The gun is a Charles Daly (Miroku) field grade 410 ga., marked “SS” over “SS”.
Thanks-a-bunch!

410 is not a gauge but the actual bore size .410 dia
Most Miroku Barrel constrictions would be marked with a series of asterix

I can tell you...(the official stats are IN!) Voting for Biden cost ALL of us $12,000/yr in inflation PLUS an average of $250,000 in lost retirement account earnings. *By making some sage adjustments, you could've made $150,000 (on avg.) back even with lackey Biden in place (-$100,000.00 loss). IF you vote OUT Biden, you'll prosper for another 4 years (and Yes, this has a dramatic effect on Safari, travel, guns, ammo, and many other related sporting industries. NO THANKS to those who voted for these fools.
