According to Brophys book , I'm kinda paraphrasing here but I'll put it in a quote anyway .
the " model 1893 " stamp on the tang wasn't shortened to " model '93 " untill 1905 .
Remained basicly the same till 1922 when the new Marlin Firearms Corporation resumed production of sporting arms after WW1.A few more options were offered starting then. ....
In 1936 the model name was changed to " Model 1936 "
