I have a question in regarding to the naming convention for Korean made vehicles from the 1950s to the 1970s before they name it Dong-A Motor.

According to the Wikipedia, they name it as Ha Dong-hwan Motor Workshop. I have it established the naming convention at the Wikimedia Commons page as Ha Dong-hwan when I discovered these vehicles posted there.

Their original title for that company as described as: 하동환자동차제작소 (hadonghwanjadongchajejagso according to the Google Translate)

https://ko.wikipedia.org/wiki/%EC%8C%8D%EC%9A%A9%EC%9E%90%EB%8F%99%EC%B0%A8#.EA.B- 8.B0.EC.97.85_.EC.97.B0.ED.98.81

However our naming convention is listed as Hadonghwan here:

What gives?
