Pricing Two Parkers

[Richard Muller]

Looking for advice on pricing 2 Parkers. These guns were owned by my great step grandfather, Charles Neuviller. I have included photos of the research letter for both guns. The DH 16 gauge, seems to be in original condition, except the LOP is 12 7/8" as my step grandfather was very short. He died in 1959 and I know this gun has not been shot since then. The VH 12 gauge has been refinished along with the LOP which is 13 7/8". Barrels have been cut to 25 7/8". As shown on the research letter, for the VH my great step grandfather returned it for repair in 1915.
Here's the back story, Charles Neuviller lived a life most of us can only dream of. My Great Grandfather and Mother owned silk mills in Paterson, NJ and after my great grandfather died, Charles married my great granmother. My great gandmother had been running the mill for some years, and wanted to continue doing so after remarrying. Charles had no interest in the business and just wanted to hunt and fish so that is what he did.
I would appreciate any guidance anyone can give,
Thank you,
Richard Muller
