I honestly dont know , some nothing . Linseed oil is really very shallow penetrateing . It was used by our military years ago. It doesnt wick well without intense heat . Wax is also surface treatment . Walnut or almond oil is good but is also expensive and a bit unstable ,( may get rancid) . Orange oil doesnt penetrate quite as good , also will darken or tint wood . Thats what i know .....What did they use before Lemon oil?
