It is a matching numbers T99 Long, with the cleaning rod.
But it is missing the AA-wings, dust cover and the mono-pod.
I think the stock might have been refinished as it is a bit too shinny, but that could be the photos.
If the stock has been refinished, that would be a big reduction in value.
As to what it is really worth, that will be decided by the bids he gets, if any.
That rifle has gone around for several months. Stock is original finish with nice marks, but is kinda banged up. Safety looks to be mismatched & the firing pin tip is clipped. Overall a decent T-99 long but way overpriced.
Well, the metal looks nice and I really like the stock even with it's dings. Still, with the clipped pin, mismatched safety and missing AA wings I'd say $600 tops. As far as the pod, I've yet to see a Nagoya with one.
