Hello Larry,

What is the configuration of each rifle?  I ma working on a survey of this Model and would like to add them into my database.   SN 51921 is most likely a counterbore Shot Only rifle based on what data I have.   SN 289371 is most likel ya standard rifle for .222 Short, Long, & Long Rifle.  https://winchestercollector.org/forum/winchester-research-surveys/model-61-research-survey/
