Parker Reproduction "Production Chart"

[SXS OHIO]

I have owned six DHE 410/28 sets, still own 2 sets. They are OO frame 28ga guns with 28ga barrels marked OO, the 410-barrel sets are stamped OOOO. Two of the sets I have owned, the 410 barrels had the same SN stamped on them as the 28-gauge frame, the other 410 sets did not have a SN on the barrels and were most likely added at the very end of production to existing 28-gauge guns. Also, none of my 410-barrel sets had a SN stamped into the for-end Irion. If the factory would not have suddenly closed, I think this would not have happened. I think the factory miss marked these 410/28 combo barrels due in part to the mini 410 stand-alone gun that was to be a true OOOO frame. There is just not enough info on that subject, and I have never laid eyes on a OOOO frame. I think the 410-barrel sets should only have OO stamped on them and there would be no confusion about the frame size. SXS Ohio
