My guess is that some of them are typos or other human errors. What I can answer is that Etter was originally classified by (Huss, 1975) as an H6. Then (Rubin, 1983) reclassified it an L5, which is how both (Grossman, 2000) and (Grady, 2000) list it. So I would say the "official" classification is L5. But this is not to say some other researcher hasn't looked at it recently and reclassified yet again. In fact because it is a fragmental breccia all of the classifications could theoretically be correct. Though I was not able to find any new sources that have reclassified it. Again I would consider the fact that the two main sources for official classifications agree on L5 and leave it at that. Grady, M. 2000. Catalogue of Meteorites. 5th ed. Cambridge U.
