I have winchester 94 pre 64 the barrel has the 30 wcf marking versus the 30-30 designation.. Does anyone know when they switched to stamping the barrel 30-30. Mine was produced in 1944 mostly assembled by women during world war 2 so the action is extremly tight. From what I have gleened these were some of the best fit finish rifles produced and not alot were made during this era. Any input would be insightfull.
