It didn't appear to me that DaveK was making the claim that SKB said that entering an Antique in the bound ledger makes it a firearm. But Dave did politely inform him that it is indeed possible to delete or negate an Antique that has been erroneously entered as a modern post-1898 gun.
I've heard SKB's excuse for entering obvious Antiques just to play it safe. By that logic, he should be entering both original and modern replica muzzleloaders just in case they might be converted to breech loaders. Or maybe he might wish to get an Any Other Weapon classification for water pipe that could be fashioned into a zip gun.
Nudge commented on the anti-2nd Amendment quotations I provided to illustrate Ed Good's (and King Brown's) views on our gun rights. I assure him those are their exact words just as they posted them on this forum. Most of their anti-2nd amendment blather was posted on Misfires which explains why they are glad that sub-forum has been locked. Now they'd like to hide from their words and pretend they support our Constitutional RKBA. Dishonesty is not civility.
