since i work ash all the time i thought i might add a few observations.
ash weighs almost, but not quite as much as curly maple, so the weight of the above rifle would be about the same in maple.
ash is a member of the olive family and when it is worked green it even has an olive smell. hickory is a member of the walnut family.
when green, ash splits very well, almost as good as hickory but the resulting splits of ash are not quite as "rubbery" as the hickory splits. they both make excellent ramrods.
aqua fortis works very well to color ash, often giving it a warm deep coppertone brown.
though usually quite straight grained, ash can have a rather dramatic curl as evidenced by the gorgious rifle above.
hope this is of value.
take care, daniel
