NIDs are very much under appreciated and bring far less than a Parker, Smith or Fox will given the same condition. In fact a beater Parker will bring more than a very nice NID. It is a shame as the NIDs have a lot going for them. Modern double, made with good materials, shoot-able dimensions and a very reliable design.

You'll get your price I suspect but it will take time. I bought a like new Smith the other day that looks to be unfired. It had been for sale for more than a year I understood from the seller. It was not cheap but I don't know that I've seen more than a couple "unfired" new which had not been redone. Basic field grade gun sales are very soft right now and I don't think they are going to get stronger any time soon.
