Like the man said above, IF the gun has NOT survived in MINT CONDITION, have it drilled and tapped for a scope and enjoy shooting the old gal. The only folks who'll pay top dollar for an early 336A waffle top want them in mint condition; and although there are those who claim other wise, these early guns are not rare. The advantages of modifying your gun for scope mounting are that you've increased it's versatility for shooting in the low light conditions of early morning and late evening hunting, you'll be able to shoot more accurately under any conditions; and with your gun having the more desirable Ballard rifling, the odds are you'll be impressed with its accuracy (especially with Leverevolution ammo). As to this alteration hurting value, if that's a concern sell it to a purist nut and buy something else; otherwise mount a scope if that's what you need to shoot well. After all, the gun ain't worth a tinker's toot if you can't be comfortable in your ability to shoot it well. And for what it's worth, the '53 model below was after-market drilled and tapped for a scope; I seriously doubt what I've done has negatively impacted value.
