Deadeye's explanation of how the pistol grip stocks were made for the later, non military rifles shows how great the workmanship was at Mass. Arms.  Another thing I always marveled about is how the carbine barrels were cut off forward of the lug, breech bored out and sleeved with the stub of a new barrel.  Good machinists of today can do it, but we are talking about the 1880's here!  I have three #16s that were originally carbines, one was a Model 1 and two were Model 2s.  You have to look close to see the joint, but it's there.  Another barrel I have has no joint and the breech face shows no trace of a sleeve being brazed into it.  So...I assume this was a "new" barrel.(?)  I guess my question is: Was this done by Mass. Arms Co. or is it an entire barrel made and installed by Stevens after they acquired Mass. Arms? Did Stevens ever convert carbines to civilian rifles? Not a whole lot of factory info available on the Maynard. But they are fasinating.

The smaller calibers, 32 and smaller were made up on surplus carbine barrel stubs. The extension of the barrel that came all the way to the breech end was only 5/8" diameter. Larger calibers were made on on new barrels. 

All the 1882 models were made up on surplus carbine frames purchased back from the Gov't. That's why the serial numbers are all over the place. I don't have any proof but I think Stevens must have made up some of the 22 Long Rifle barrels. The Long Rifle came out in 1887 but was not in use much until 1888 and Maynard was on the tail end of their life. Long Rifle barrels were listed in the 1890 catalog.

That is not necessarily a 1st Mod barrel. That filled dovetail seems more likely to have been for a scope mount of some sort. 1st Model frames were made for the Maynard tape primer and have the door to cover the pocket for the roll of primers. Here's the only picture that I have ever seen of a 1st Mod converted with an 1873 hammer that seems to be a factory conversion. I've seen some Rube Goldberg conversions.
