Ralph,
I am there and did that. Just this month I had a NM3 in 44 Russian shipped to me from the US via USPS no problem. Spent 1 day in Canada Customs before being released to Canadapost.
What you are dealing with is known in Canada as a Prescribed Antique Firearm:
Regulations Prescribing Antique Firearms
As you can see the regulations have no rhyme or reason. They are however government policy enacted to prevent gun crime, as in drive-by shootings.
At the present time, a Canadian can't buy, import, sell, give away, or bequeath a hand gun. They may own and shoot them at a government approved range, if the firearm is properly registered with the government, they are properly stored according to government regulations, and the owner holds a valid firearms license for restricted or prohibited firearms. When the owner leaves his mortal body, the handgun will be confiscated by the government for destruction with no compensation to the estate.
So far these regulations with the exception of storage do not apply to Prescribed Antique Firearms.
Jean Chretien (Prime Minister) turned every person possessing a gun into a criminal in 1995. Read criminal code of Canada Section 91.
All guns in Canada were prohibited in September of 1995, when the Jean Chretien Liberal government amended Section 91 of the criminal code to make possession of any gun a criminal code offense. The Firearms Act (Chapter 39, Statutes of Canada) creates the gun license (PAL). The gun license is only a temporary (5 year) amnesty from conviction for possession of any gun.
The only reason the gun license exists is so the anti gun owner bureaucrats can recommend that guns be removed from the protection of the gun licence and the Prime Minister uses an OIC (Order in Council) to remove the protection a gun license gives.
That is what happened May 1, 2020 when the Liberals prohibited 1500 brands of hunting and target sporting guns in Canada. They lied and called them assault rifles (Assault rifles were prohibited in 1978 in Canada)
Bill C 21 seeks to end legal possession of many hunting and target rifles as well as the legal possession of handguns in Canada.
The Liberals prohibited one half of the handguns in Canada as of February 14, 1994 (retroactive from December 1, 1998 when C68(1995) came into effect) and now they are prohibiting the other half with Bill C 21.
Law abiding gun owners?
Gun owners buy a license to defend themselves from criminal charges for possession of property deemed a criminal code offense.
Liberal MP (Member of Parliament) Pam Damoff "gun owners are law abiding until they are not..." Law abiding ends when the gun license (PAL) expires or is revoked for a class of firearm like the May 1, 2020 OIC (Order in Council) prohibiting named firearms and ending the power of the license to protect from criminal charges for possession. All Firearms can then be seized and held, charges can be laid, and only a court order from a judge can force the police to return the firearms - Section 337 of the criminal code requiring that property of citizens seized by federal agents be returned on demand was rescindedt in 2018 by the Liberal government.
Here is a link the Firearms Reference Table (FRT) which will give the Firearms Reference Number (FRN) for your NM3. As you can see, some are considered Restricted or Prohibited and cannot be imported, and some are considered prescribed antiques and can be imported. The various Restricted and Prohibited NM 3"s are mainly due to calibre. You will also note the FRN changes depending on barrel length.
See:
Canadian Firearms Data & Analytics | Armalytics
At the present time in Canada, all NM3 frames are considered to have been manufactured BY 1898. If you include a factory letter stating your revolver was SHIPPED in 1898, or later, this might trigger overwhelming waves of confusion in whatever Customs Agent reads it. It is still a Prescribed Antique by regulation.
Here is a link to the FRN for the NM3 so you can find the proper FRN for your barrel length:

This is most likely more than you ever wanted to know about the sad state of Canadian gun ownership.There is more but I haven decided to show mercy and omit it.
There is no 2nd Amendment in Canada, but it appears the rabid anti-gun sentiment is creeping south.
If you were in my shoes, you would be tempted to put prescribed antique (no mention of firearm) in the customs declaration or anywhereon the outside of the parcel.
You would include documentation in an envelope affixed to the outside of the parcel that included Make, Model, Serial #, Calibre, value (if any), and the correct
FRN for whatever barrel length your NM3 has.

I would then cross my fingers and hold my breath.
Some more to chew on while holding your breath.
Canadpost regulations for individuals shipping firearms:
Personal | Sending | Canada Post
These regulationsare for individuals shipping firearms within Canada. Your USPS parcel will be delivered to Canada Customs, who will release it to Canadapost if they are in a good mood.
The Canapost regulations are for individuals and don't apply to a business. My NM3 was shipped USPS from a auction house.
USPS-Canada post is hands down the cheapest way to ship for the person you are shipping to as they only charge a $10cdn import fee. You will want be sitting down you see what UPS or FedX charges the recipient for import fees. A licensed exporter is hundreds of dollars.
Hope when your head stops spinning you will find this info of some interest, if not use.
Regards.
