Here is a picture of the NEF Survivor. The stock is butt-ugly (pardon the pun) but functional. It's marked SB-1, so it's a cast iron shotgun frame. The serial number prefix dates it to 2006 and it's marked New England Firearms, made shortly before the acquisition by Remington in '07. Rem. killed off the NEF name and reverted to H&R 1871. Yes, the H&R website is still up but who knows why. Information is out that all production of H&R 1871 products ceased in 2015. I don't know all the history of the acquisition but NEF had been taken over by Marlin in 2000 and operated as a separate unit. I'm just guessing but maybe Remington wanted Marlin, didn't care much about NEF/H&R stuff but got it as baggage in the transaction. I've owned a T/C Contender .45 Colt/.410 bbl. before in the past. Plus several other bbls. but I've found that I can't shoot the Contender well and mine will be going away shortly. I'm already down to just the .223 Rem and .41 Mag bbls. NEF made a standard SB-1 shotgun in .410/.45 Colt, I had one of those about 10 years ago. It had the lightly rifled barrel and same kind of choke. I don't remember the wrench being marked T/C but if not, it was made the same. This is a picture of the fancy ammo I bought recently: Below is my DeLuxe Topper H&R that I got new in 1966. .410 bore. Didn't need a recoil pad, came that way from the factory. Now it's hard as a rock, just a spacer. Also my NEF SB-1 in 28 gauge, made in 1992. In addition, I've got an SB-2 (steel rifle frame) which is .223 Rem., they called these the Handi-rifle. Different bbl. configurations were available for .223, this one has a short but heavy profile. At the breech it looks like a scaled-down naval gun, very thick. In the past, I also had one of these with the thin taper bbl. in .223, never could get it to shoot as well as the one with the heavy bbl.
