THE INSIDE DIAMETER OF THE APERTURE IS 4/16 . My sight is tight and not wobbly at all . I appreciate all the info and if some one has one I can try PLEASE LET ME KNOW !!! I will also contact the pother source listed in case . Yes I heard about all the cracked stocks . I took mine apart and used some spar varnish and tung oil to the inside areas that appeared dry and possible weaker areas subject to cracking . I have some 35 Newtons loaded up but they are on the heavy side ,so never shot it, yet . I will probably have some lighter ones loaded first to try it and yes I always wanted to shoot it .I agree its quite slim but that really is the charm of the rifle . I would say this one has been shot a little so its good it did not crack . I almost thought when I first got it , it had a rose wood stock as Newton had some like this as it has a nice rich red color with black grain but its probably just nice walnut ,still I had a rose wood stocked rifle once and it does look some what similar Not sure how to post pics here ? If anyone emails me at willsanders@earthlink.net I can send you a few pictures if you can post them for me . The 35 is by far the rarest of the normal Newton calibers . Production now looks like less than 300 . Who knows how many are left and how many of those are unaltered .
