The "changeover" started about 1913-1914 and ran until 1931 when the 3rd model was introduced.
We have volumes of research on the IHC 185 site. When you are wanting "research" go to the top of the main page and on the left side is the "Find-Or-Search" heading. left click on it and a drop down box allows you to type in what you are looking for. In this case you might put in "2nd model 992". Try and keep your request with fewer words and be sure and spell correctly and you will have access to more information than you can shake a stick at !!
