I managed to convince Steve (bouldersmith) to part with this beauty, as of today it lives with me.
26" barrel, 7lbs 5oz, and 14 3/8" length of pull.

Action is a Greek 1903 (Steyr 1909) production, 6.5mm London proofs as pre 1925, and an Austrian "T in a circle" indicating special grade steel supposedly used on or after circa 1920.
Bolt release is a button.... thus 1924 or before.
So according to the "T in a circle" on action and barrel, London proofs, and bolt release it most likely was made between 1920 and 1924.

However:
Barrel is roll stamped "Sighted & Shot by W.J. Jeffery & Co. Ltd. 13 King St. St James London SW and serial number".
The 13 King Street address is said to have been closed in 1914

Roll stamped on the barrel with an old stamp? Or?
So.....the date mystery will have to wait for an answer from the business that holds the Jeffery daybooks.

1st thing was clean the bore and go over the details. Bore is unworn bright & shiny from end to end.
The Jeffery peep sight is in perfect working condition along with the rest of the mechanicals.

My major discovery is that this 1903 is not a .256 Gibbs Magnum at all......it is a nice unaltered standard 6.5x54MS.

100 PPU brass and 2 boxes of Privi Partizan ammo are now on order. I have plenty of 160 grain Hornady roundnose to share with my Wm. Evans 6.5x53R.

More to come when I get it shooting.
