DHE 12 Gauge Vent Rib:

[Bruce P Bruner]

The safety was tight with no wiggle. The special order code 11 does not indicate a single trigger. Why would a selective trigger be refitted on a shotgun with identically choked tubes? Both tubes are full choke.
Of the 7 or 8 Parkers I've owned every one's inner for-end had near new remaining case color, that's not the case on this one. For that matter every other one had evidence of case color at least in the protected areas, here again this one is largely devoid of remaining case color, just subdued blotchy shadows. The butt stock finish exhibits a good amount of "crazing". The lock-up is very tight.
Given the expense to get the gun in shooting condition one has to rationalize whether it's worth it. I believe the head on the butt stock can be repaired and the rest of the gun could be left as is and it would still be a desirable gun. One could go with the "full house" restoration and end up with a very lovely shotgun. Consider that the barrels require no attention what so ever other than some oil on a rag, the expense of repairing the stock and perhaps a stock refinish would put the investment at (guessing) <$5K. In my opinion you could shop for a long long time to find another one at this price point.
One of our members has reached out and indicated that if I pass on the purchase he would like to purchase it. I have no problem with passing the details on to the Library Manager. This means there is at one person that thinks this example is worth the time and investment. As always I appreciate everyone's help here.
