If you mean the hand work in assembling a gun, CSM was selling the kitted parts for the Ithaca NIDs from the remnants of the New Ithaca Gun co. a couple years ago. Now it looks like they're all gone.
You will likely be able to find a kit for sale at some bigger gun shows that someone bought. But you'll find few that have been started, and fewer that were ever finished. I know one that was finished.
If you want one, put a want ad in this site's classified section for one. They were $795 when sold originally, with no wood, if I recall correctly.
