Craig with all the confusion about the barrel material etc. I would really like to hear form the owner, after all one mans semi pistol grip is another mans "Prince of Wales". If this gun truly has a round knob grip then I think it can pretty accurately identified as a DS or I grade that didn't get the grade stamp. If on the other hand it has a capped grip I think we can be pretty sure that with twist barrels and dolls head barrel extension it is an H grade that was improperly assembled without cocking indicators unless of course this is a "Lunch Box" gun then all bets are off.
