I just traded for one of these, earlier this year, m'self...bout $60.00 worth of ammo...figured it a good trade.
Mine's a Glenfield, too....got a straight 4x same branded scope offa ebay for roughly $20; have removed the "hump" on the stock; still refinishing it with the girlfriend's help; made in 1978, I think. Maybe I'll post pics when it's done.
It's my first Marlin/Glenfield, and I really love the way it's turning out...if you like yours half as much, bet you love it! I think it may beat out my various 10/22s as my favorite "squirrel gun"...
