Factory ported .375 H&H No1?

[awp101]

Youngest boy bought a 1997 production .375 H&H No1 (Tropical I think). The barrel is ported but I don’t know if it’s factory or not. The ports remind me of Magnaport but it’s not marked as such.

My limited googling hasn’t turned up anything but I may have overlooked something. Anyone know if there was a factory ported No1 or what I should look for to determine who may have done the work?

Thanks!

I've collected #1s for well over 30 Years and never heard of a ported model.

The 450 Bushmaster did come with a Muzzle Break and Threaded Cap...

Thanks! I didn’t think it was factory but we all know to never say never when it comes to Ruger.

I HAVE PLENTY OF MNP'ed HANDGUNS AND T/C HANDGUN BARRELS AND AS FAR AS I KNOW MNP DOES NOT "MARK" FIREARMS OR BARRELS THAT THEY JUST MNP.

I totally forgot they do full builds so it would make sense those get the logo instead of the random porting only job that comes in.
