Personally I have never seen a Steyr with qnw subcontracted parts such as the floorplate and triggerguard. It also appears to be in the incorrect stock and bands. It also appears you have an S block bolt but a T block receiver?
Not sure what you did to clean it but the rule of thumb is most the time, unless there is something damaging the rifle like active rust, do not touch it, especially the wood.
Regardless of the mismatched parts, everything there IS excellent, for example the stock and band set is great and stock looks like it has nice sharp bolt cutout still, which would be great for another rifle. do the stock and bands match each other? It appears the rear band has a serial number, which may match the SN in the stock channel. 900 is a great price still, but I'd say you have 2-3 great starting points for rebuilds, not 1 great rifle.
