You might find a 983 out there but it may take awhile.
I have a 2008 model 983 :
Marlin shows a Model XT-22MTW on their website:
It looks pretty much like my 983 but has the newer Pro-Fire® Adjustable trigger where my 983 has what was called the T-900 trigger. I notice the checkering pattern is a bit different as well.
I have not personally seen or inspected a new XT-22MTW but did take a look at several of the new XT-22 magnum models in my local gun shop today. The fit and finish was as good on the three XT-22 rifles I looked at as on my JM stamped 983. The actions worked smoothly and barrel and sight alignment seemed to be right on. Now all of the rifles I looked at today had synthetic stocks so I can't make a comment on the quality of the walnut.
There are a few folks here in the forum who have purchased the 22 magnum version of the XT-22 recently so hopefully they will chime in for you.
