I think owning consecutive serial #'d guns is neat, but that's just me
I own two set's of Ithaca NID's that are consectively #'d, 2 fully optioned 4E 20 gauges and then a 3E and 7E 12 gauge. Often wondered if they shared time on the work benches up there in Ithaca, probably did. I really need to do letters on the the 2 - 20's, maybe ordered together.
Don't own any consecutive Parkers, hopefully some day.
