Shawn, The gun appears to be a 1903/1914 style. (There is no Model 1906 - that is just the year the patent was granted). I am quite sure any 1903 bolt would fit but the correct bolt for this vintage would probably have been the version with the improved & stronger extractor that was mounted on the outside of the bolt. Bolts will be found with either an open or closed loop that goes on the action arm, either will work.

It is interesting that your gun still has the early type action lock rod, it changted slightly in later guns and if you put an early type arm in a late gun you will never get the receiver halves back together,

The gun looks great, worn but clean - hopefully they just want it put back inworking order and not 'restored', that would be a shame on this rare of gun. I have two Gold Medal grades earlier than that one and when compared you can see some real differences in the engraving on mine. I can get you some more details if you need them.
