B1987, I think you're young and inexperienced. So we will be gentle with you.
The rifle you mention is a sporter, with a new or altered stock. It may be fine as a hunting rifle, but it no longer qualifies as a collectabe milsurp.
If you want an original 1903 Springfield in one of its various configurations, I would suggest you save your pennies (no pun intended) and look for an original rifle. There are several gunshows comeing up in BC soon. The next one of mention is in Chiliwack at the Heritage Park facility off Hiway I. Mar 14/15, 9-5 saturday and 9-3 sunday. Get there early on sunday because most of the vendors are getting packed up to go home by 1:30pm, some may already be gone by then, depending on how far they have to go.
As far as Eddystone Pattern 14 and Pattern 17 rifles go, they are the most prevalent of the series. For $450, you should be able to find a very good to excellent grade rifle, with matching numbers and made by Winchester or Remington. The ERA (Eddystone) rifles were also made in a Remington owned factory. For an original 1903 Springfield, expect to pay twice as much, maybe slightly more.
Just a snippet of extra information, The US issued more P17 rifles dureing WWI than Springfield 1903s.
Also, a huge quantity of the P14, P17 and 1903 rifles were either lend leased or sold to many countries between the wars and after WWII. They show up all over the world, still being used successfully in 3rd world bush wars.
I'm under the impression that there are warehouses in Europe, South America and Africa with many of all grades Enfield P series and Springfields, still in storage. Maybe just wishful thinking on my part to. Many were just used and abused to death and long since turned to scrap.
