Pre-64 Model 70 Fwt. .30-06 (the only kind Winchester made in those days) with 165 Partitions--the old kind.
Dang, you were pretty sophisticated as a youngster.
Mine was an A-Bolt medallion in .30-06. That was before I realized I was taking my life into my hands by shooting an A-bolt. Don't remember the ammo, but it was factory 180s.
I still have it, but I sanded off the glossy finish on the stock and oiled it, looks much better now. It was always a shooter.
