Please Help IN iDENTIFICATION OF Barrel

[ringo]

Evening , I am researching a barrel I recently purchased  the seller could not help . The barrel is a factory Thompson Center Encore barrel in 45-70 Gov. , 24" , stainless steel , 45 cal. , set up for smokeless powder , the breech plug looks like a Savage breech plug including vent liner . There are no markings telling the builder or any info . If anyone recalls a person or builder doing these conversions I would  like to know , I have a few questions and I would like a source for parts . Thanks

I suggest you post question under the Savage / Smokeless section. I believe several had this conversion done
