Need Advice Getting a Neglected M1917 Sporter into Shape.

[Surpmil]

Could it be one of these? .303, I know but they seem to have done .30s as well. Think I see a Canadian ownership mark on the receiver ring.

Good spot. So undoubtedly one of the many rifles brought up from the USA as Lend Lease in WWII. AFAIK none of those .3006 rifles were taken to the UK or used there by Canadian troops, so probably the chop was done here in North American post-war.

No sign of the action being drilled and tapped as per the advert?

OP: I think what you've got is a decent quality action you could rebarrel and build something out of if your sentimental attachment to it is strong enough; otherwise it's a "parts car" for someone else.

All manner of magnums were built on these actions, although some may have been re-heat treated in the process, as there were issues with some early rifles, Eddystones in particular.
