NEF and H&R are the same company, the Sportster is an NEF product, just as is the Handirifle. The Ultras and several other products are H&R products, both companies are one under roof as H&R 1871 LLC, which is owned by Marlin.
http://hr1871.com/About/default.aspxTheir current products don't include a bull barrel 22Lr and to my knowledge, never has.
The top pic is a 17hmr or 17M2, both of which have bull barrels, no sights and monte carlo stocks. The bottom pic is a 22Lr or 22mag, it has sights and a straight combed stock.
