Saw that rifle a few years ago at the winter Vegas show, think Terry Buffum owned it. Then at the next show (not sure of sequence) Monte Mandarino had it. My recollection, for what it's worth, is that it had a Lyman 103 on it, not the current 52A. And somewhere along the line the price was 9,000. It is quite splendid. Interesting that it is a varmint calibre but not set up for scope sight.
The sight/varmint caliber question is interesting. I have a lovely C.C. Johnson highwall .225 stocked in walnut by Hal Hartley that has a 1 1/4" Unertl with the same rear sight. I always kind of wondered about it.
