It's impossible to evaluate something so special and unique from pictures alone it must be held and examined in person. If brace of guns was for single "rough shooter" I would expect choke combo for one 1/-4-1/2 or 1/2-full or something similar, but for two person team 1/4-full makes very good sense taking very good advantage of two triggers and two barrels. One does not come across charmer sold by family members of original owner a lot making it a little more special, but if the "shoe doesn't fit it doesn't fit". How the guns fits and feels to the shooter is also important because bringing down birds is also important.
PS. If you don't buy it I would think it would be worthwhile to find another Canadian buyer. It would be a shame to export something like this out of the country if it can stay there.
