Hey Loy,
Got a Garandlast year from the CMP
, came with new Birch wood stained an ugly brown. Hand sanded the stain off with #220 grit paper. Re-stained with a 50/50 mix of Minwax walnut and red oak stain. Finished with three coats of hand rubbed pure tung oil from The Real Milk Paint Co. I'd do the same with walnut unless it came with a nice color. Just my preference.
