Given that Greeves used proprietary engines of a variety of displacements and cylinder configurations, I think it would be useful to add columns for "engine manufacturer", "engine configuration" and "engine displacement". Unfortunately, I don't have the time to do this now, so if anyone else would like to take it on, please do so. Otherwise, I'll try to add them later. Bricology (talk) 18:44, 19 February 2014 (UTC)
