Besides Austin and Halleck, does anyone make a nice looking accurate inline?
I know A&H is pretty much out of business. I am aware of the NEF Sidekick too. I have no interest in the Encore.
I take it you don't mean laminate wood? Not too many that use walnut anymore.
There are several very good old inlines that can be had for a song, like Knight MK-85, T/C's older inlines, even the Knight DISC rifles had walnut. Some of these old guns can still be bought NIB, if you check around and are not in a hurry.
