My William Evans sidelocks, stocked to the fences, full crossover, Scott patent screw grip locking, 12 gauges, are as true a matched pair as any I have ever seen. After 100 plus years, they are even matched in very high original condition. Gold numbers one and two on the top levers, consecutive serial numbers, cased in Evans oak and leather case. I know there are lesser "matches" but these are true matches. They are my dedicated sporting guns and I shoot them alternatively every week. I was able to afford them only because they are crossover guns. Two straight stocked guns would have cost me more than twice what I paid for this pair. What was the question again?
