The NID he posted photos of though not a true Lefever is nice, but still an upgrade.
The subject gun of this thread was the "Up-Gradsed"?? gun marked Lefever Arms Co, Ithaca NY. I assumed that was the gun Old COL was referring to as he chastised those who "Got off Thread".
As such it is a Nitro Special, Not an NID. An NID would not carry the Lefever name on it.
If in fact he was referring to the NID which was shown as an example then I apologize. I believe though it would still not be classified as an Up-Grade as it does not follow the pattern of higher grade NID's
