Don't be dismayed. I bought one in worse condition -- a sporterized skeleton with only an original butt stock, stripped receiver (like yours), and cut-down barrel. I bought a second sacrificial No.4 Mk2 skeleton with a good barrel but with a butchered receiver that had the charger bridge cut off. Total preliminary investment -- about $200.
After assessing all the restoration options, I sent the skeleton sniper and the sacrificial Mk2 to our stalwart sniper restoration expert in the US -- Brian Dick. (I just don't have the machine shop rigs necessary for cutting and remounting barrels, precision taps to drill out the old telescope mounting holes, etc.)
I told Brian I trust him -- do whatever you feel is necessary to make it whole. Brian has the package of skeletons now. (You might consider the same option.)
To me it's worth spending the money to make such a rare gun whole again. Had the gun been an average Enfield it wouldn't be worth it and I wouldn't have bought it.
Of course, now I now have a cut down barrel and a butchered receiver left over. I'm open to ideas on what to do with the left over parts. My first inclination is to use them to create a "tanker carbine," which has a somewhat limited market among those that want a pickup truck gun. Anybody have a better idea for leftovers? (I can't fathom the thought of scrapping Enfield parts, even if Bubba got to them first. )
