How do you find them? Do you know by heart or do you have some way of remembering the profile while browsing the catalogs? I haw tried myself, but even when I think I have found a match, I'm uncertain...
This one:

I have identified as either a JMA RU-KD or a JMA RU-11D, none seam to fit perfect, but both are darn close... :/ What would you say?
