Impossable to say without you providing a serial number to your Model 30aw.
If you are asking when it was made?Then the serial number indicates the year of 1997 as to when it was produced.
Your Marlin model 336 AW which was made in 1996 will bring between 200-400 dollars,depending on overall condition and a good bore.
$350-400 in PERFECT shape.
250-375 dollars depending on overall condition of the rifle in question.
from $150 to $350
All that I can say is that the marlin model 336W/30AW were made during 1983-2007.Most of these were sold thru Wal-Mart.
I believe that the marlin model 30AW(all weather) stock was a walnut finished birch stock.
MSRP new was $447.00. The serial tells that it was made in 1995 (first 2 #'s minus 100). You could get between 340-400 if it is in PERFECT shape.
prior to the year 2000 the marlin model 30AS was a way for marlin to distinguish that the rifle with the AS was a part of the glenfield line of guns,which were made with a walnut finished birch stock.The same applys to the AW except this also indicated all weather,meaning synthetic stock.
Jeanette Aw is 38 years old (birthdate: June 28, 1979).
Its basically the Wal-Mart version of the Marlins.However there is nothing wrong with the gun at all,the only difference is the wood.Instead of having a Walnut Stock,it is just stained to match Walnut.So to answer your question AW stands for American Walnut stained...
