Yes
The forearm is the most noticeable alteration to the yellowboy.
Because the Henry has the slot on the bottom of magtube, no forearm could be fitted...
Some Henry's were altered by gunsmiths in the field, kings patent loading gate, and wood forearm...
Yellowboy also had a stronger brass frame, and small improvements to the internal action... All to make the action strong enough to fire 44/40 rimfire.
And side loading of course...
The sweet 73, had the Iron (steel) frame, and Centerfire ammo...
No other type of rifle has ever had such a natural feel...
They mount to your shoulder easily, and seem to point right where
needed, like magik....
I just prefer the original design... so clean!!!!
