This was the end of the line as far as Kodak's production of cameras for its 620 film (6cmx6cm negatives). In the US the Reflex 20 was produced between 1959 and 1966; in the UK the production run was a slightly shorter 1960-1965.
This book is easily the most comprehensive book on HIT-type cameras there is. If you're serious about collecting these beautiful creations, make sure you grab a copy.
Superb.

This is the lightbox I use to photograph all cameras on this site. Highly recommended.
While the majority of photography podcasts - both audio and video - focus on the gear, in The Art of PhotographyTed Forbes takes a close look at the various aspects of creating great photographs. Everything from explanations of concepts such as ‘rule of thirds’ and ‘depth of field’ to how pinhole cameras work (and how to make one). A tremendous mix.
If you love taking photos, regardless of what type of camera you’re using, whether you’re shooting film or digital; check out The Art of Photography podcast. Highly recommended.
