HP Classics: About Cases and Boxes

[isanchez]

Hi everybody,
I am trying to put in order my HP collection. I have doubts about the assignation of hard cases and pouches to different HP classic models. I have not seen this in the website, so maybe could be of help.
As far as I know, from my experience "surfing" in eBay, there are three types of Hard-cases for classic models:

Grey plastic small size: for HP35 only (early models:1,2 or all?)
Grey plastic big size: for HP35 (types 3&4 or none?), 80, 45, 70, 55 & 65 models
Black vinyl small size (luxury): for HP80 & 45 models, only?
Cardboard box: HP67/97 (no hard case for this model at all)

About the pouches, I have seen four types:
-Black leather model with velcro and pocket: supposed to be in the small hard cases? mainly bended in a roll with a elastic band. For 35, 80 & 45 (all when bought in small sized cases?)
-Brown leather-like model ("Hewlett Packard" vertical orientation) with zipper: for all classic models, except 65 & 67
-Specific leather black pouch with velcro and front pocket for hp65
-Specific brown leather-like pouch with internal pocket & zipper for hp67 ("Hewlett Packard" diagonal orientation)

Please, make remarks or corrections.

Thanks in advance,
Kind regards
