Excellent suggestion: practical, brief, uses a clear description. Dave is right that the "industry" term isn't always descriptive enough to distinguish physically different parts. The "Murphy roof" is my favorite example, a term used by the P.J. Murphy Co. and then by Standard Railway Equipment Co. for at least 50 years, applied to dozens of roof designs. At the least, you'd have to qualify it by year (or decade, or something) to achieve a useful distinction.
