I have a few questions about a new to me Parker

[Tennessee Dave]

Ok, so I got the letter for this GHE today. It says it was completed in 1921 and was a GHE hammerless, 12 ga. with 28-inch Damascus barrels. Stock with capped pistol grip with LOP 14-1/8, DAC 1-3/8, DAH 2-5/8. Weight 7lbs. Price was $129.00
What would the chokes be if it says it was patterned RH 125 pellets and LH 225 pellets of size 7 shot in a 30 in. circle at 40 yards? I was surprised that it didn't tell anything about who ordered the gun, but at least it is as originally configured.
