Richard,
Here's my thoughts & these are only my personal opinions.
Just looking at these as indivdual DHE repro's I feel the value in todays market would fall like this.
The 12ga & 20ga three barrel set would probably sell somewhere around $5000.00 to $6000.00 each. The 28ga $6000.00 to $7000.00 The .410 $8000.00 to $11,000.00 (.410's are really hard for me to call)
This adds up to a value of somewhere between $24,000.00 on the low side & $30,000.00 on the high side.
Then due the rarity of possibly being the only four gun same serial numbered set made. I would say add at least 10% and possible up to 25% for the set.
Then there are unknown variables of configurations of these guns. I.E. triggers, two forearms per set, straight stocks, wood quality etc.
That's my opinion for what ever it's worth. I know I'd sure like to see some pictures of this set !!!!!
