NOT a Savage 219 Barrel -- So what is it? (pics)

[Red Hill]

Hello,

I picked up this 30-30 barrel as part of an auction lot. My first thought was that it was a Savage 219 barrel.

It is not marked, other than caliber ".30-.30 CAL. WIN." and what appears to be the s/n 7118.
Google images showed no 219 barrel with the same lug profile.

Thinking that folks here might recognize it and know what it fits.

Apologies for the poor pics.

Thanks.
