Origins of 22LR

I’m sure this has been discussed here previously…which company should get credit for introducing the .22 LR and when ??

Most “sources” credit Peters Cartridge Co. working with J.Stevens Arms Co., circa 1887.

This seems at odds with UMC having cataloged the LR in 1886 and J. Stevens was selling UMC cartridges (including .22 LR) until 1900.

There was here a very useful thread (to me at least) on this very topic a year ago, or perhaps a bit more. I think a search for older posts will turn it up. Jack
