Fore-wood has cut-out for clip-loading bridge (Rifle No.1 Mk.II or III), but action and bolt are Lee Speed or Mark 1?

If the stock is not correct, maybe other parts are assembled from mis-matched time-line as well...

Mark.VII ammunition introduced around 1910.

Early Lee sporters are very good things IMHO, have several myself, but prefer complete replacement of dog-leg buttstock with a higher comb to put the shooter's eye behind the sights. Significantly reduces perceived recoil as well.
Cheek-weld, not chin-weld.
