Howdy Again
I can agree with that. I would go so far as to say cleaning the 1873 is a lot easier than cleaning the 1892. When shooting Black Powder in the 1873 Winchester, if one is not using a WCF cartridge, such as 44-40 or 38-40, which seal the chamber better than the thicker brass of cartridges such as 45 Colt, all one has to do to clean the mechanism is remove the side plates with one screw. The entire mechanism is then accessible for cleaning. That can be seen in the photos I posted earlier.
A lot more has to be taken apart to completely access the mechanism of the 1892.
To be completely honest it has been a long, long time since I took one of my 1892 Winchesters (I have four of them) apart to that degree. I would have to look up a disassembly manual if I was going to attempt to do it again. But if one is shooting Black Powder 44-40 or 38-40 cartridges in an 1892, it does not really matter much, because they seal the chamber so well that very little fouling blows past the shell in the chamber. What little gets in there can be easily cleaned without a total take down.
