Hmmm you link showed what looks like a Parker-Hale Supreme .303 sporting rifle which P-H did for many years. They are of course converted ex-military Lee Enfields but completely re-finished with slightly shortened barrels drilled and tapped for P-H mounts and stocked in Walnut often supplied by SILE. In June 1973 a newly converted one would have cost you £21:15 which roughly equals $38 US. As for stocks like the Supreme ............................. well I am sure that at least some of the US stock makers still supply sporting wood for them, however please be aware that bedding the LE is not the same as other bolt action rifles but if not right effects the accuracy just the same, but there must be those experienced in bedding them at the stock makers I would hope.
