I have an opportunity to buy a new Holland and Holland Royal 20 Gauge cased from the early eighties. It is worth it to consolidate down to a smaller number of guns to have the Holland? I love the gun but I am just not sure of what to do. I would have to sell several of my best 10k pieces to get it. I can put some money on it but it would be tough to give up part of them. Any perspectives? Thanks, HuntersDad
