Pre-1898 gun NFA question

[Ron3]

Does anything go as far as pre-1898 guns?

I'm guessing you can't make/buy machine guns. But can you change caliber? Shorten rifle/shotgun barrels under 16/18 inches? Neither?

Just curious.

The real question is what exactly are you trying to do and / or got in mind ??

I've been told you can't do anything that would come under the term 'manufacture', as that then changes the classification.

In my case this involved Stevens tip-up pistols w/ long barrels, where the original date of manufacture is suspect due to the loss of records after Savage Arms acquired Stevens and the early records were tossed.

Nothing interesting. A pre 1898 single shot shotgun. If it's cut down under 18 inches is it still an antique non-firearm or become NFA?

Then I started wondering about other pre-1898 guns.
