Thorny,
Good guns, like grouse, are where you find them. American classics, are overrated for sustained use, and the common mans ammunition hasn't helped this one bit. Show me the single trigger Parker or LC Smith, and I will show you a nuisance. And, a cracked stock, usually. Hence, the good stuff is selling for a bundle. That is not the same as worth a bundle. That Boss was a gentleman's gun, and received good care, and proper ammunition over the coarse of it's life. Usually. More usually than anything from over here, anyway. A well cared for Boss is NOT a rarity. A well cared for Yank, really is.
Best,
Ted
