Remington Pump Model 14 & 141 Cartridge Stops




The model 14 rifle was made from 1912 to 1935 in calibers 25, 30, 32, and 35 Remington.  The model 14 1/2, made during the same time frame, sharing the 14's serial numbers, which was basically the model 14 modified receiver but made only in 38-40 and 44-40 calibers.   We can not find a part number for any model 14 1/2 parts, but simply the model 14 parts list with a note, "specify caliber".   So to clarify things on our part we have assigned the 14 1/2 cartridge stop with part #238 1/2, (who knows, this may even have been what they used).  These guns were made in a lesser quantity & seldom seen.  

Later when the model 141, came out, it is the same basic gun as the model 14, utilizing a more modern pistol grip stock and fuller forearm was made from 1936 to 1950 in calibers 30, 32, and 35 Remington.

These guns all utilized a cartridge stop that floated in a slot between the barrel and the magazine tube in the front of the receiver.  These stops were held in place on the front by an "action bar cover" which was attached to the front of the receiver by a small screw.   Basically the model 14 uses the #238 stop, with the model 141 the #638.   However there seems to be late or transition model 14s that use the later 141 stop. 

Part # 238 Part #638 Part #238 1/2

As best as we can determine they started using the larger cartridge stop (#638) as standard on Model 14's somewhere near S/N 117xxx.   There however has found a smattering of older guns (S/N  321X,  29xxx, 77xxx) that have the #638 stop in them.   Neither 321X or 77xxx will function with
the smaller (238) cartridge stop.   It would appear that possibly these older guns were retrofitted with the newer stop at some later date.  We have yet to encounter a 141 with a smaller (238) cartridge stop.
It is known fact that when some manufacturers come out with a new modification, they just threw the new parts in the assembler's bins on top of the older ones and the assembler/fitter would have to set aside the older parts until there is enough to assemble a gun, which makes for some later guns showing up with the early parts.  

The cartridge stops are specific to each version AND caliber.   We have seen these stops with numbers stamped on them ranging from #1 to #4, and after measuring many of these, but never getting any size relationships to the numbers, our conclusion is that this firearm was made back when each gun was hand assembled, if machining tolerances were great, they just installed a larger size and fitted it as needed.    So if it is a late 14 and the stop becomes lost, you might well have problems even deciding which it takes, but the chances are the #638 may function if fitted using the gauge shown below.  

After many years of stumbling trying to fit these parts and trying to make the firearm function, we were going thru an OLD gunshop that was selling out it's parts inventory, we found a set of factory GO / NO GO fitting gages.  This was confirmed later by the Remington factory repair dept. supervisor.  These are one set for the 25 / 30 / 32 and another for the 35 Rem.  They are made like a regular cartridge, but with the diameter being the same as the case for the GO and oversize for the NO GO.  They are hardened with the rear dia. ground to the specified diameter.  These were threaded, attached rim end to rim end to a  3/16” Z shaped rod.  Electric pencil engraving is "Rem 141  mag well gauge MIN .462   35 cal", on one end, with the other end simply says "MAX .467".  The 30 caliber sizes are MIN .425 and MAX .429.

Factory original tooling 

From this, it is apparent that factory new cartridge stops are all made oversize, then had to be fitted to the individual gun for functioning.  In use, a new unfitted stop is installed, these gages are slid thru the loading port with the action slid rearward, trial and error is used by removing metal until the NO GO gage will fit.  Then file off slightly more, maintaining the same angle until the GO will just slide by.
