Deerslayer you're exactly right. Glenfield and Marlin is the same as Stevens and Savage for example. If I were looking for a .30-30 and found a Glenfield, I would not hesitate one bit about buying it. Glenfield 30A's were produced from 1973-1983, back when Marlin made better quality products than they do today IMO. So you'd simply be getting Marlin's "heyday" quality in a little plainer version.
