Whip - I've owned a couple of older firearms, one a revolutionary war musket and the other a 1874 Springfield - both had beautiful stocks, made more gracious and lovely by the passing of time, the perspiration marks of those who carried them, the darkening by gun oils and the dings, dents and scratches imparted by long and hard use. And they were still gorgeous. Just using a lightweight oil to clean the stocks brought out grains and beauty marks (boles, I think) that really made these common-place stocks of yesteryear look better than anything I have seen short of a custom stockmaker's dreampiece.
I think that curly ash stock on your Marlin is going to age the same, if you give it a chance. I really like that particular Marlin - the barrel length is the same as the one I had. If I were to find another one I would do to it what I mentioned in the last post, and then I would add an eye-catching stock. Sure it is going to get used, and that is the beauty of it.
On a tangeant, my Hornaday Handbook shows a range of IMR4198 charges from 35.8 at 1700'/sec to 45.3 at 2200'/sec with a 265 gn bullet from your rifle. The VithaVuoryOy boys use 48.1 gn of their N120 and 51.3 gns of their N130 for 2320'/sec with that bullet. I've used the VV powders and they meter very nicely and are consistent in performance - very accurate loads.
I hope you use that Marlin for many years to come. I hope that stock wears into your style of carrying and shooting and ages so gracefully that when you (hopefully) pass it on to another, that stock and all the effort you have put into that rifle carries your huntin' spirit with it down through the future generations that will use it. Mikey.
