Several years ago I was fortunate to be able to purchase 2 of Mike Walker's rifles. The first was his Mod 37 rimfire and the other was his favorite deer rifle. It was an early 1948 production 722 in 257 Roberts.
I would like to attach photos, but my 81yr old mind ain't figured it out. The 722 has a Lyman Alaskan 2.5 power with a post and swing away mounts to allow you to use the iron sights. The mod 37 has a barrel mounted 8X power I believe Lyman Target Spot. I know how to email photos, but cannot post them here.
