All three are most often caused by a broken striker and lifter assembly, a broken or stuck firing pin, a weak, broken and/or dirty mainspring, or a dirty action. The most common problems with this firearm are failures to extract, broken extractors and failures to fire. They need to be driven out from the right side through the left unless someone has changed them. The five pins in the frame are directional, and came from the factory driven in from left to right. The three pins in the barrel lug are roll pins, and can be driven out either way. These firearms use six wood screws, one tang screw (stock bolt), and a forearm screw to hold wood to metal but all the metal parts are held together with pins. If the breech release is not on the top left side of the hammer, you have an older model or variant. Again, these numbers will also apply to some older guns that have different internal parts. It will also include single-shot rifle Models 258, 157, 58, 158, 163, and 155. Writing this is like trying to write one service manual for all the Fords ever made without distinguishing which model is which, but it can give you some tips that will make repairing these single barrels easier. Using an exact scale drawing of the needed part, along with the model and serial number, can help. Needless to say, this is one of the hardest shotguns to get the correct parts for.
When they did start using them, the same number was often used again when the earlier model went out of stock.
Then you have to deal with the fact that H&R had little if any use for part numbers in the beginning. Model numbers also crisscross several times, and H&R even adds “A” to some of these models. The internal design of the early model gun is completely different from the later model 148. The same number is also used on an earlier model with the old-style opening lever located on the shotgun’s tang. The reason for this complication is that, despite making many changes in the shotguns through the years, H&R has not kept its model numbers separate.Ī good example of this is the Model 148, a late-model firearm with a breech-lock release on the top left side of the hammer. Simplicity has always been the key to these single-barrel shotguns, but they are anything but simple if you factor in identifying which gun gets which part. The shotgun action we will use for this chapter is from one of the company’s latest model series. Harrington & Richardson made single-barrel shotguns for more than 100 years, and the basic design didn’t change when New England Arms took over.
