I have the Glenfield version. Has a beautiful engraved stock but is essentially a Marlin 336W.
Are you sure that is the 'W' model? I thought all of them had a scope mount? I actually inherited mine from my father (Truth be told I'd rather have my Dad than the rifle but it's a nice keepsake). It actually was sold with the scope mounted already. Oddly, the Glenfields were the "bargain" version sold in Sears despite the engraving on the stock.
Regardless, it's an awesome rifle. Not sure the 30-30 would be my first choice as a deer rifle but it's a fun gun to shoot and is surprisingly easy to handle and lug about.
