The auction house also sent me some pictures of the bolt, they could not get the bolt to close, maybe the bolt was assembled wrong by the last person who took it appart. But it does show the serial number and the serial number on the bolt head is the same. Thank god no Bubba has been swithcing parts around.
The bolt assembly looks to me to be from a GEW 88 Commission rifle or a Steyr 93 (Romanian) contract rifle,not a Mannlicher Schoenauer.
Absence of the bolt guide rib on the bolt body is a good clue. Neither of the above use one. The Dutch 95 Steyr does.
All three of these use the straight line feed en-bloc 'clip' loading system and have the magazine extending below the stock.
The bolts are all very much a like and some parts will interchange as well as some with the Steyr Mannlicher Shoenauer bolt assembly
The flattened bolt handle on this one looks like an issue German GEW 88 Carbine bolt.
The rifles had the standard round knob straight handle bolt.
(Steyr) Mannlicher Schoenauer uses a bolt guide rib on the bolt body extending forward of the bolt handle root.
Both on Military and Commercial actions.
GEW88 & Steyr (Romanian) 93 bolts do not have the bolt guide. The Steyr (Dutch) 95 does have the bolt guide on the bolt body.
(The Dutch 95 was also made in Holland at Hembrug Arsenal.)
Commercial M/Schoenauer bolts will have a small 'V' detent projection just to the rear of the root of the bolt handle. That is for the bolt lock spring to ride over and hold the bolt closed when in the down position.
The bolt lock spring is dovetailed into the right rear side wall of the receiver on the outside. Easily seen. It as well as the 'V' detent on the bolt body was omitted on the Military contract actions from Steyr and those made at Breda in Italy.
In the pics posted originally, the bolt lock spring is clearly present (commercial action), but there is no V detent behind the bolt handle for it.
None of the Steyr straight line feed bolt actions or the GEW88 used the bolt lock spring that I can recall.
Just my observations.
