I remember that the 219 cocks when you push the lever to open the action. That makes a fairly hard lever to throw. I believe Ed said that the 220 (or 221?) cocked themselves when you closed the action. Again, another variation and a slightly different action. I'm going to have to find a site that can tell me what all the variations are. 44 Man
This is the site.
FWIW, Model 219's (no letter suffix) and early Model 220's all have internal strikers, cocked via the opening action of the top lever.
Any early or late barrel will fit/operate properly in an early action.
Model 219B's, 219C's, 219L's and 220B's & 220L's all have an internal hammer, cocked via the lifting of the front end of a cocking rod that lies inside the forward RH receiver sidewall.
"L" models lift the front of the pivoted cocking rod via the side lever, all others lift it via a protruding spring-loaded cocking stud built into the side of their barrel's underlug(s).
Only late barrels, with the cocking lug, will operate properly in later guns - the early barrels will not work in later guns, because they lack the cocking lug, making barrel removal a necessity after one shot, for manual recocking.
Please don't bother to ask me how I learned this to be fact.
