Around here the simple, sporto'd Dutchies occasionally are found, lost and bereft at gunshows.
I recently got a few basic quotes, to assay a one off project similar to small commercial idea you post.
First: find the best specs for a properly dimension chamber,to milled into a good bbl with the modern .256-260-264 dimension. Dave Manson makes premium reamers and that's who my gunsmith wants me to buy from. Also, he would only use a Shilen or comparable first quality bbl. I empathize with him, as I find lesser quality antiques to take just as much time as an untouched , signed Stickley desk upon which somebody once mounted a can-opener.
D&D Gunshop, up the road in Mich also will do this work. they grind their own reamers to y'r specs-- $140.00 Tobbl up with a Douglas bbl is 460$, including the bbl. Installation of NEGC express sights, and other goodies will be 'per item' wished. They do a fine. sharp bead blast with a double hot-dip. Looks a lot like a rust blue, but is very durable.
As to stocks, there are some good dupe'rs, even in my neck'o the woods. I'd guess a thou would fetch one in,depending on what the purchaser is willing to accomplish -- action polishing, wood finishing, furnishing parts..
An economy of scale could be realized by subscription,but I won't hold my breath. The first realistic mfg step is to get the reamer made, and that is the one I'm, oddly enough, doing first. Prolly, the Manson, tho certainly benchrest quality isn't necessarily needed. Then the reamer is available for rent, to those so minded. Ordinarily, I would just loan for free, but given that Iwould have no control over where or how it used, it seems prudent to spread out the cost, JIC there is an upp-effin incident.
A couple of thoughts, and some heresy. I have owned a No4 Golden States Arms sporter which had been re machined into a ver' nifty and teaditional shape, sans loading and ears, and rear sight stuff. I like No4's 'cause they a half century newer than anything of quality, but Aussie No1's. Something to think about as anyone witha solid vice and metal working hand tools can replicate that look on some poor old Gomer'd action. Also, a good tight No. 4 can push 48,000 CUP -- a discussion for another time.
However, Lithgow No 1's which have been thru the gentle hands of Bubba are out there and relatively inexpensive. Mo' classic lookin's, if ya will. Prolly easier to get a sorta Lee-speed look, too. I gotta run back to the money makin',but willbe happy to discuss this at length with interst'd parties. Exchange of E-addys and we can do that by phone?
