The Marlin .30-30 is awesome. [8D] I have an old Marlin 30AS version of the 336.
The difference in mine is just cosmetics, as I don't have the hooded front sight
and thesame style of forearm endcap. Here's mine:

I read your other post in the optics forum about scopes for the .30-30 and replied to that
as well. I had an old Glenfield 4x32 scope on my Marlin .30-30 and ended up taking it off.
The legendary, historical, old .30-30 just seems to look better without a scope. But that's
just my opinion... If you scope it, just put an very low 1-4x32 scope on it with a low set
of rings.

The .30-30 is a 50 to 100yard classic deer rifle that shines in the heavy woods and brush.
I still hunt with mine when I don't use my Savage .308 (with scope), which is setup for
longer distances. I know Hornady has the new LeverEvolution ammo, that is supposed to
be fantastic and turns the .30-30 into a 200 yard gun, but I haven't tried it yet. I wouldn't
want to try shooting 200 yards with open sights. My Marlin 30AS is setup at 50 yards with
the rear sight elevation, and that's where I leave it.

Edit: Oh BTW... Welcome to the forum!
