The bolt pictured is pretty much what a Dutch 95 Mannlicher bolt looks like except a M95 has the bolt guide rib on the body.
It's a different bolt head from the M/S.
Same for the M93 Romanian Mannlicher and the GEW 88 Commission.
I believe the one in the picture is a Karbine bolt from an 88.
Neither of these latter two have the bolt guide rib.
A Military M1903 Greek (or Breda mfg) bolt assembly will be the same as the commercial bolt assembly for a 1903 Mannlicher Schoenauer. It will be made for the 6.5x54 cartridge.
It will NOT have the bolt lock peak at the rear of the handle as the commercial bolts do however (the action pictured is a commercial).
You can see the V shaped peak on the bolt just to the right of the bolt handle base in James-I's first picture of his 1905 bolt.
They also lack the cosmetic feature of the very fine knurling on the top surface of the cocking piece and the spoon shaped bolt handle.
The 1903 bolt head is made for the 6.5 cartridge which has a smaller case head diameter than the other M/S cartridges.
Find out what's up with the rifle first inside before buying anything else. The DST is there in the pic, but there's a 'kicker' sear also inside that needs to be there.
If the rotary magazine is incomplete, Greek Military parts can be used as substitutes in the commercial 1903
Original bolt assemblys are very few and far between. Original Commercial parts of any type are hard to find but then again it ain't a Remington 700.
