This list is known to contain errors in the prefixes, but has handy info on the model letters and displacements not in the other lists. There is a definitive list of that too, and at some point I'll have a shot at combining them all so when you find that dung covered Ariel in a barn on the west coast of Scotland (what? I thought that's where they all came from!), you'll be able to figure out what it is. In the mean time I'm leaving this one here because it is mostly right.

Thanks to the folks at Accessory Mart for letting me scan this from their catalog. More will get entered soon, now that I know how to scan tables into the OCR software. The above is not fully proofread yet, but is pretty close. 29 years done, 4 to go.
