Do the Henry's have plastic sights and barrel bands?
Not any more, the older-production rimfire guns had those and there really wasn't anything wrong with them, as plinkers. HRA responded to a few years of bellyaching and came out with a metal replacement in the last few years - but the Octagon barrels have always (as far as I know) had a metal sight in the dovetail, not a plastic barrel to magtube connection that also mounted the sight.
I gather from what I've read in other threads that the "yellow" on the Henry is rather soft brass that scratches very easily.
It isn't brass, it is a brass-colored coating - and it isn't indestructible.
The OP wants a wall hanger and occasional range toy, not a club to beat a bear to death with right before winning a blue ribbon for "most attractive finish"
Because they're ugly and overweight.
Are you talking about me again? < raspberry >
I don't think they're ugly at all, but they are heavy. And they lack a loading gate. And I'm not a fan of brass-colored guns in general, but I still think the Big Boy models are appealing.
I'd prefer if they came in black the same as the 30-30 version, preferably with the pre-mounted aperture sights like one of the 30-30 models ... I have to be very careful not to encounter one of those, as I already stock 30-30 and wouldn't have an excuse to NOT buy it.
My suggestion:
Get a Henry "big boy" model and a "mares leg" in the same chambering, and mount the BB above the ML on the wall along with some .357mag ammo and leather gear - other than Rossi's ranch hand, I don't think any other manufacturers are making a "handgun" size to match their rifles/carbines.
