While what you are saying is accurate for 22’s built after 2012, here are our thoughts…
Marlow purchased Hunter Marine in 2012 and changed the company name to Marlow-Hunter at that time. The new version 22 was launched in 2010, two years before, and was simply called the Hunter 22. As we can not give two records the same name, we added the -2 designation to differentiate the new version form the original 22 launched in 1981.
Changing the name of records years after they are created is problematic as it will effect search engine results as well as bookmarks which will cease to work. For this reason we only do it when absolutely necessary.
As the original name of the 2010 model was Hunter 22, not Marlow-Hunter 22, we feel the best solution in this case is to leave the record as it is. We are confident, in doing so, anyone looking for this record will still be able to find it with minimal effort. We hope you agree.
