I kinda do know the history of the hollowbody models, but how do I explain it..? Let's see:
Basically they appeared in about 1998, and most of them died off in either '01 or '04, with only the Hollowbody II continuing past that. (And then the 594 HB II appearing, and even later the SE HB's appeared.)
• If it's got the name "Hollowbody," then it's going to be a 3" thick body at the bridge [1-3/4" thick at the sides].
• If it's got the name "Archtop," then it's a thicker 4" at the bridge [2-3/4" at the sides].
• If it has a "II" in its name, then it's going to have flamed maple top AND back ("II" = two maple tops) with mahogany sides.
• Without a "II" in its name, it'll generally have a mahogany back.
• If it has "Spruce" in its name, it'll have a spruce top; otherwise assume maple top.
There is a random Archtop "IV," which has a spruce top and maple back; but for the most part everything's going to pertain to the aforementioned bulleted classifications. Match together any combination of the words "hollowbody" or "Archtop," and "II [or not]" and/or "spruce [or not]" and you've got yourself a unique model.
