Winchester made several versions off that platform a semiauto, lever's for certain and I think a pump.
My uncle had a lever version of the 190, the model # escapes me right now, I later on brought back like model from the dump's & was able to get a replacement barrel for it, it turend out to be just as inaccurate as my uncles dur to not having proper turque on the retaining nut.
my guess is if one does assemble them correctly to the right torque use locktite to set the nut.
For info please query the gunsmithing or rifle Numrich Gun parts forums
Ive since sold my .22 lever gun but can recall that somebody from there forums were able to get me contact information with a guy in Arkansas that stocked parts for allot of winchester post 64gun parts 'pin together guns'.
